01. The Man Trap
Professor Robert Crater and his wife Nancy are archeologists, investigating the ruins of a civilization on M-113. Enterprise visits for the annual physical examination required by regulations, but the professor seems oddly reluctant. He insists all he and his wife need is salt to cope with the heat. Then Crewman Green dies, his face marked by odd red rings. Crater says he ate the borgia plant which contains toxic chemicals. But its symptoms do not include the red mottling. Kirk and Spock are determined to discover what's going on, and doubly so when a crewman on the ship dies the same way as Green.

02. Charlie X
A small ship, the Antares, transfers a passenger to Enterprise. He is Charles Evans, recently recovered from the lifeless planet Thasus, having survived there since he was marooned by the crash that killed his parents. Oddness seems to accompany Charlie. Antares calls, with a warning her captain does not finish delivering before his ship explodes. Soon enough it becomes clear that Charlie is a young man of extraordinary powers, able to cause things to happen merely by willing them to. Kirk must regain control of his ship from a troubled, dangerously powerful teenager.
September 22, 1966
03. Where No Man Has Gone Before
Enterprise recovers the pitted and burned emergency buoy from the wreckage of Valiant which penetrated the odd energy barrier that surrounds the galaxy. Garbled recordings suggest odd consequences of that journey, and even that Valiant's own captain ordered her destruction. Enterprise also visits the barrier, and it has odd effects on certain members of the crew with high esper ratings. One in particular, Kirk's friend Gary Mitchell, appears to have developed nearly godlike mental and physical abilities, and lost his moral compass as well. Now Kirk must discover how to stop - and maybe kill - his old friend before that becomes impossible, and Mitchell goes on to conquer the Federation!
September 29, 1966
04. The Naked Time
Psi-2000 is a lifeless, frozen world in the final stages of planetary disintegration, an invaluable opportunity for scientific study. But the entire scientific outpost complement is dead, apparently by violence. And soon enough, an odd intoxication of similar nature begins sweeping through Enterprise, threatening all of the crew and even the ship itself, as intoxicated crewmen lose all sense of duty and purpose. Worse, McCoy's investigations reveal no causative agent, limiting his ability to treat those affected.
October 6, 1966
05. The Enemy Within
An odd, yellowish ore with magnetic properties on a crewman's clothing affects the transporter, and when Kirk is subsequently beamed up, he is split into two "halves". One half of him possesses his benevolent qualities, but is indecisive. The other possesses his malevolent qualities, but is afraid. At first the crew is unaware of the problem, and Kirk's reputation suffers. Then they realize what has happened, and that the transporter is useless - just when they need to bring back the remaining planetary expedition before the sub-zero night kills them! And they must discover how to "reassemble" the captain when it becomes clear that neither half can survive for long without the other.
October 13, 1966
06. Mudd's Women
The Enterprise recovers Harcourt Fenton Mudd from within an asteroid belt. His crew is also his cargo - wives for settlers on Ophiuchus III. These women are very beautiful, and have oddly compulsive effects on the male crewmembers. Having burned out most of her dilithium crystals protecting Mudd's ship, Kirk detours to a Rigel mining colony to secure more. But Mudd's women secure a communicator for him, enabling him to strike his own deal with chief miner Ben Childress and his associates. To obtain the crystals, Kirk must bring down Mudd's women, and must agree to dismiss charges against Mudd. Added to the mix is that the women may not be all they appear to be...
October 20, 1966
07. What Are Little Girls Made of?
Roger Korby, described as the "Pasteur of archaeological medicine" has built a reputation recovering the knowledge of dead alien civilizations, until five years ago when his entire expedition was lost on the frozen world Exo III. Or was it? When Enterprise assumes orbit, someone using Korby's voice responds to their hails. It seems Korby discovered that the civilization of Exo fled their ice age by going underground. He has uncovered some of their science, including their machinery for producing hardy androids - and for transferring a consciousness into such a machine. And he has plans for that technology. Ambitions, sinister plans...
October 27, 1966
08. Miri
Enterprise discovers a planet identical to Earth, with a very important exception: a few centuries earlier, a devasting plague struck. All of the adults were killed, but the children somehow survived - and still survive, hundreds of years later, feral and deeply distrustful of "grups". And there are monsters: insane, covered with scab-like plaques, they attack on sight. The disease is still active; the plaques appear on the landing party. If McCoy cannot discover a cure in the week they have left, all will die. Even Spock, now a carrier, cannot return to the ship.
November 3, 1966
09. Dagger of the Mind
Enterprise stops at the Tantalus penal colony to deliver drugs and collect research materials. Except that the research materials box contains a dangerous madman, Simon van Gelder - the former director of the colony. Kirk and psychiatrist Helen Noel beam down to speak with Tristan Adams, to learn what happened to van Gelder. It seems Dr. van Gelder was the victim of a new device, a neural neutralizer. But was what happened really an accident, or something more sinister?
November 10, 1966
10. The Corbomite Maneuver
Mapping star systems, Enterprise encounters an odd cube. Apparently solid, it senses the ship, moves to block it - and when Enterprise attempts to disengage, pursues while emitting dangerous radiation. Kirk is forced to order its destruction. He probes farther, to find the builders of the device. And he does, when the Fesarius appears. The immense flag ship of the First Federation and her captain, the enigmatic Balok, regard the destruction of the cube as an aggressive act, and determine that the crew will be imprisoned and the ship destroyed.
November 17, 1966
11. The Menagerie Part I
Spock diverts the Enterprise to Starbase 11, where Kirk discovers that Spock's former commander, Christopher Pike, has been seriously injured and disabled by exposure to delta rays, experienced while saving a class of cadets. Pike is now confined to an elaborate life support apparatus. Spock abducts Pike and locks the Enterprise on a course for Talos IV, the only planet subject to General Order 7: visiting the world is a capital crime. Spock refuses to explain his actions, but demands a court martial, during which he presents evidence of an earlier visit. War, thousands of centuries ago, devastated the planet, and it was only now becoming able to support life again. Its inhabitants, forced underground, had developed enormous mental powers, including the ability to place illusions within the minds of others. Their plan was to breed a race of slaves to help them reclaim their world, as they were fragile and their civilization degenerate: illusions had proved a kind of narcotic. To this end, they kidnapped Captain Pike years ago...
November 24, 1966
12. The Menagerie Part II
As the court martial continues, Kirk learns the Talosians meant to breed Pike with an earlier survivor, Vina, to produce their slave race. But Pike convinces them that Earthmen would prefer death to such slavery, however pleasant illusions could make it. Humans were the Talosians last chance, but Pike convinces them to release him. Finally, as they orbit Talos, Kirk learns why Spock violated General Order 7: here, in his illusory world, Pike can live out his remaining years as the man he once was. The Talosians agree to this, and the Federation suspends General Order 7 due to the circumstances.
December 8, 1966
13. The Conscience of the King
Dr. Leighton calls Enterprise to his home on Planet Q with the promise of a new food source that could end hunger. But this is a ruse: Leighton is one of the few remaining survivors of Kodos the Executioner, who used a planetary famine to apply his own ideas of eugenics on Tarsus IV years earlier. A burned body convinced authorities that Kodos had died then, but Leighton is certain that actor Anton Karidian is Kodos. Kirk is less than amused at the deception - and then someone murders Leighton. It's not enough to accuse, but it is enough for suspicion, so Kirk arranges to strand the acting troupe, and then offers them a ride on Enterprise where he hopes to ascertain whether Leighton's accusation is true.

The Enterprise tries to intercept a Romulan warship that is testing the Federation's defenses along the Neutral Zone separating the two.
December 29, 1966
15. Shore Leave
Enterprise visits an idyllic planet, where McCoy encounters a large white rabbit that is "very late". And shortly afterwards, a little girl who is following him. McCoy isn't becoming insane; it soon becomes apparent that thinking about a thing will cause it to materialize, as everyone encounters people and things from their past or their fantasies. But something on the planet's surface is draining power from Enterprise. And then McCoy, convinced that what he sees is a harmless illusion, confronts a charging knight - and dies, pierced through the heart! What kind of odd world is this, and how can the ship and crew escape it?
January 5, 1967
16. The Galileo Seven
Enterprise is en route to the New Paris colony to deliver much needed medical supplies, needed to counter a plague. It passes Murasaki 312, a quasar-like system. Since there is time, Kirk's standing orders require him to dispatch a scientific team to study the phenomenon. The expedition immediately runs into trouble when it is pulled off course and forced to an emergency landing on Taurus II, then beset by the hulking, homicidal natives of that planet. Can Spock's purely logical approach to leadership save the expedition and reunite its members with Enterprise?
January 12, 1967
17. The Squire of Gothos
Within a "star desert" the crew encounter the odd, storm-wracked planet Gothos. Then Kirk and Sulu disappear from the bridge. The planet's sole inhabitant is the foppish Trelane, who lives in a manor house be believes represents modern Earth, but which is actually centuries out of date. He has plans for the crew, and the power to ensure that he gets what he wants. Kirk manages to thwart him, but it's only temporary: Trelane moves Gothos itself to intercept the fleeing starship! Against that kind of power, Kirk will need all his wits...
January 19, 1967
18. Arena
Enterprise stops at Cestus III, there to visit Commodore Travers, who enthusiastically invites Kirk to bring his key people to the surface. Beaming down, Kirk discovers the outpost has been destroyed! The landing party comes under attack, but Kirk and Spock recover a powerful ballistic weapon and strike back. The aliens flee, with Enterprise in hot pursuit, into an unknown region of space. There, both ships are paralyzed by an "unidentifiable power" from the distant star system of the Metrons, and both captains are transported to a world where they may engage in hand to hand combat to determine the fate of their respective ships. But is that the whole story?
January 26, 1967
19. Tomorrow Is Yesterday
A "black star" slingshots Enterprise back in time, to the 1960s, in Earth orbit. She appears almost directly above a military base, which draws all sorts of unwelcome attention. The base dispatches Major John Christopher to look. Enterprise attempts to keep him at bay with the tractor beam, but his aircraft is too fragile to withstand the beam and disintegrates, forcing Enterprise to beam Christopher aboard. Now they have disrupted history. Christopher himself is not historically significant, but his son is. He must be returned, but how?
February 2, 1967
20. Court Martial
Enterprise encounters an ion storm, which requires an observer in the ion pod. Top of the duty roster is Commander Ben Finney, who is tragically lost when Kirk must eject the pod as part of the Red Alert protocol. At the starbase, Commodore Stone discovers that the computer records tell a different story: that Kirk ejected the ion pod during Yellow Alert, and that if he had waited properly, Finney might still be alive. He offers Kirk a chance to resign his commission "for the good of the service", but Kirk refuses - and so draws a general court martial. His advocate? The quirky Samuel Cogley, who eschews his computer in favor of books.
February 9, 1967
21. The Return of the Archons
Six thousand years ago, the planet Beta III was torn apart by war, crime, and corruption. Then a visionary leader arose, Landru, who became a benevolent autocrat. He has maintained a simple, stable society that has survived since then without those "ancient evils". Enterprise is there to investigate the disappearance of the starship Archon in the vicinity a century earlier. It seems that Landru dislikes those who display individuality; they must be absorbed into "The Body" or destroyed. So it was with the "Archons" and so it will be with the Enterprise unless Kirk can defeat Landru. But will unseating him destabilize the society? Will it be a violation of the Prime Directive?
February 16, 1967
22. Space Seed
The Enterprise chances across a DY-100 class ship, launched from Earth "in the 1990s". It carries around seventy people, who have been hibernating since their launch. The ship's systems revive the leader, whom Kirk soon learns is Khan Noonien Singh, the leader of a group of genetically enhanced "supermen" who nearly took control of Earth during the Eugenics Wars. They have essentially fled to the future, and with their capabilities, Khan plans to revive his campaign to place "superior" men in positions of leadership.
February 23, 1967
23. A Taste of Armageddon
Kirk and the Enterprise have been sent to establish diplomatic relations with the planet Eminiar VII, a planet that decidedly does not wish such relations! But Ambassador Fox insists they make the attempt. Planetside, they learn Eminiar has been fighting a war with Vendikar, another planet in the same system, for five hundred years - a war fought entirely by computers, with casualties required to report to disintegration machines for tidy disposal. And the Enterprise has been declared a casualty of a "tricobalt satellite explosion"; her crew must likewise report for disintegration so their deaths may be recorded and reported to Vendikar.
March 2, 1967
24. This Side of Paradise
The Federation established a colony on Omicron Ceti III before it knew that the system's star emitted Berthold Rays, which degrade animal tissue. Tolerable for short periods with precautions, these rays spelled doom for the colony. So how are they still alive, and in better health than when they left Federation space? And perhaps more importantly, why have they accomplished... nothing? The answer threatens the Enterprise...
March 9, 1967
25. The Devil in the Dark
Miners on the mineral rich world of Janus II have begun to die horribly, burned to a crisp by the effects of a powerful corrosive. The Federation depends on these mines to supply minerals to many other worlds, so it sends Kirk and the Enterprise to investigate. But a starship, as one miner acerbically comments, cannot enter the mining tunnels. Kirk and Spock will have to use their wits to solve this problem. And they'll have to do it quickly, since the same agency has sabotaged the antique pergium reactor that maintains life support.
March 23, 1967
26. Errand of Mercy
Kirk and Spock transport to the planet Organia, a pastoral realm of very low technology, which has the misfortune of being strategically important to the Klingons, who plan to use Organia as a forward base when they war on the Federation. Despite Kirk's best efforts, he cannot seem to impress upon the Organians that they are in dire peril and should ally with the Federation. Then the Klingons arrive, and being imposing martial law, and taking and executing hostages. Kirk works behind the scenes to interfere, but when the Organians betray him to the Klingons, he starts to wonder if they are worth protecting.
March 30, 1967
27. The Alternative Factor
An alien named Lazarus is somehow responsible for a kind of "winking out" effect - all of reality seems on the verge of collapse. He is fleeing a monster whose intent is nothing less than the destruction of reality. But through a mishap, Kirk is transported to the home of that monster. And he looks exactly like Lazarus! Kirk must decide which of them - if either - is the monster. If he guesses wrong, it's the end of everything.
April 6, 1967
28. The City on the Edge of Forever
Ripples in time have provoked the curiosity of the Enterprise crew. One such ripple shakes the ship and gravely injures Sulu. McCoy brings him back from the brink with a powerful drug, but another ripple results in a tragic overdose, afflicting McCoy with dangerous paranoia! He beams down to the planet - the transporter was locked onto the source of the time disturbances. On the surface, he evades the landing party long enough to flee - into the past, where his psychosis results in him somehow erasing the Federation, and the Enterprise, save only the landing party. Their one chance is to use the same artifact - the self-styled Guardian of Forever - to arrive before McCoy and prevent him from changing their history.
April 13, 1967
29. Operation: Annihilate!
Approaching the planet Deneva, the Enterprise encounters a private spacecraft whose pilot is flying desperately into the sun, the apparent act of a lunatic. Spock reveals disturbing news: a pattern of mass insanity that has spread across the galaxy in a nearly straight line, the current end of which is Deneva. The landing party discovers the horrifying truth - and one of them becomes its victim. Now the crew must devise a cure before Spock dies, or is driven hopelessly insane.
September 15, 1967
01. Amok Time
Spock is becoming increasing irrational, even threatening to break McCoy's neck! He can't or won't explain this behavior to Kirk, only asking to return to Vulcan. It's a request Kirk cannot grant, given the Enterprise's other business. Until McCoy tells him if Spock continues to deteriorate, he will die in days! Kirk makes the decision to take his friend back to his home world, where he learns that Spock's problem has to do with marriage...
September 22, 1967
02. Who Mourns for Adonais?
Enterprise nears the planet Pollux IV, when an immense humanoid hand appears and seizes the ship! It is not actually living tissue, but a complex field of energy. And it belongs to a being who claims that he and his kind visited Earth long ago, and were then revered as gods - in this particular case, the Greek god Apollo. His request is a simple one: the crew of the Enterprise will depart the ship and establish a colony of worshippers. Of course, Kirk has no intention of doing this; he must make "Apollo" understand that humans have moved past him.
September 29, 1967
03. The Changeling
A space probe of immense power and sophisticated technology has apparently annihilated the entire Malurian civilization, and now threatens Enterprise. But when Kirk hails it, the attacks cease and it allows itself to come aboard. Soon enough, the reason for its forebearance is revealed: it mistakening believes Kirk is its creator, Jackson Roykirk. This probe is Nomad, launched from Earth long ago. But its technology is far beyond what was understood then; beyond even what the modern Federation is capable of. What happened to Nomad, and why does it destroy whole civilizations?
October 6, 1967
04. Mirror, Mirror
The Halkans are a people deeply committed to peace. Kirk is trying to negotiate with them for dilithium, the rare mineral that's needed for warp power systems. But if there is even a chance their crystals will be used for violence, they cannot agree. Kirk beams back to his ship as a magnetic storm approaches - but the ship where he materializes is vastly different, run by savage opportunists, sadists, and killers. This ship, part of an Empire, will wipe the Halkans from their world and seize their crystals. Kirk must find a way to prevent that, and to return himself and his landing party home.
October 13, 1967
05. The Apple
Gamma Trianguli VI is a peaceful planet with abundant plant life. It seems a paradise, but the landing party soon feels the thorns: poisonous plants, killer storms, and explosive rocks all claim lives. Eventually, they discover a small community of primitive people who serve the mysterious Vaal, an immense statue, chiefly by feeding it when it demands this. These people live immensely long lives, and do not age or procreate unless there is an accident. Theirs is a stagnant society, and into the bargain Vaal apparently has the means to attack the Enterprise...
October 20, 1967
06. The Doomsday Machine
Enterprise discovers the wreck of Constellation, a sister ship. The only survivor is Matt Decker, the Captain. He reports beaming his crew down to the fourth planet - except that there is no fourth planet! He investigated an odd occurrence: a planet apparently disintegrating, and discovered an immense space vessel cutting the planet apart with an antiproton beam, and digesting the pieces! This machine came from outside the galaxy, a relic of a devastating war fought long ago and far away. It will carve a path of destroyed solar systems through the most populous part of the Milky Way unless Kirk and his crew can stop it.
October 27, 1967
07. Catspaw
Sulu, Scotty and Jackson explore Pyrus VII, and then Jackson calls the ship, "one to beam up". He materializes dead, and a sepulchral voice threatens Kirk, saying his ship is cursed! Beaming down, Kirk discovers his men enslaved by strange aliens, who have created a Gothic castle and other artifacts straight from Halloween. But their power and threat are real - they are from a place so alien, that the sensations of this universe are intoxicating. If not stopped, they pose a grave threat to the Federation.
November 3, 1967
08. I, Mudd
Mr. Norman is a new crewmember whom McCoy finds off-putting. He acts like a Vulcan, which is odd in a human. There's a good reason: Mr. Norman is not human. He is one of a collection of androids sent to hijack Enterprise by Kirk's old adversary, Harcourt Fenton Mudd! Mudd has plans for the starship, grand plans. And so do the androids.
November 10, 1967
09. Metamorphosis
Enterprise sends a shuttlecraft to retrieve Federation Commissioner Nancy Hedford, who suffers from Sakuro's Disease, so that she may be treated. The craft is pulled off course and lands on a small planetoid, where the crew discover the systems will not work. They also discover a man, apparently living alone there - or, is he? He seems to from time to time commune with an energy cloud, the alien being responsible for forcing the shuttlecraft down. It means for the crew to serve as companions for the man - forever.
November 17, 1967
10. Journey to Babel
A large diplomatic conference will take place on Babel, to discuss the contentious issue of whether to admit Corridan to the Federation. Delegates are divided, and some of their motives are less than pure. Among these delegates is Sarek of Vulcan - Spock's estranged father. Add a mysterious challenging spacecraft and a murderer aboard the Enterprise, and Kirk has his hands full. Then Kirk himself is stabbed, leaving him seriously injured at the very moment when Spock is due to donate blood so that McCoy can operate on Vulcan ambassador Sarek's damaged heart. The key to solving this puzzle will require deducing which of the many factions is willing to go to violent lengths to sabotage this conference.
December 1, 1967
11. Friday's Child
The Federation sends Kirk to negotiate for mining rights with Aka'ar, Te'er of the Ten Tribes of Capella IV. Capella IV has deposits of the rare mineral topaline, needed for life support systems. The Klingons need this mineral, too, and their presence creates tension further complicated by conflict among the members of the tribe. Ma'ab murders Aka'ar and becomes the new Te'er, and he has a decidedly different attitude that favors the Klingonm perspective. Worse, Kirk and McCoy will not stand by while he murders Ele'en, the pregnant wife of the old Te'er, despite this being Capellan tradition. Soon enough, the Federation party is running for the hills - literally - with Capellans and a Klingon in pursuit.
December 8, 1967
12. The Deadly Years
Enterprise discovers the scientists on Gamma Hydra IV are all either dead or dying of old age, despite the fact that the oldest was around thirty! Matters get worse when the landing party begins to show signs of aging, all except for Chekov, who is mysteriously unaffected. Eventually, Kirk must be relieved of command, and as Spock and Scotty are both affected, Commodore Stocker assumes command. But Stocker has been a desk officer his entire career; he has no field experience, which leads him to make a desperate, wrong decision...
December 15, 1967
13. Obsession
On an obscure planet, Kirk smells something that reminds him of the past. And then two crewman die, their ghastly pallor betraying the fact that every red blood cell in their bodies has been destroyed, the hemoglobin neatly removed. A long time ago, very far from here, Kirk was a young Lieutenant about the Farragut when that ship encountered the cause: a mysterious, gaseous cloud that feeds on blood. Now, Kirk is obsessed with destroying the monster that killed his then mentor, the Farragut's captain Garrovik. Perhaps to an unhealthy degree. Or, given what Spock discovers, perhaps not.
December 22, 1967
14. Wolf in the Fold
Kirk takes Scotty to Argelius, a planet renowed for hospitality. Scotty is still recovering from serious injuries accounted to a female member of the crew, so McCoy is concerned he might harbor subconscious resentment toward women. But apparently not; he takes a young woman for a walk through the fog. Kirk and McCoy leave later, and en route to another tavern, hear a high scream. They arrive to find Scotty, bloody knife in hand, standing over the body of the young woman, who has been stabbed dozens of times! They're certain Scotty is innocent despite the evidence, but proving that will require them to discover the actual murderer - and reveal a horrifying truth from history!
December 29, 1967
15. The Trouble with Tribbles
Under the terms of the Organian Peace Treaty, Sherman's Planet will become a colony of whoever can best develop it. To that end, the Federation intends to ship a large quantity of quadrotriticale to that planet, and Federation Undersecretary Nilz Baris is determined that the grain will arrive, so he orders the manager of Space Station K-9 to issue a distress call! Enterprise responds to discover no emergency; Baris just wants guards for his grain. And then a Klingon ship arrives, seeking shore leave. And Cyrano Jones, an itinerant trader, also arrives, with some odd animals he calls tribbles. Some very hungry, odd animals...
January 5, 1968
16. The Gamesters of Triskelion
Kirk, Uhura and Chekov are set to beam down to examine and maintain a communications relay station, when they vanish from the transporter room in a way inconsistent with normal transport! They have been whisked across planetary systems by the mysterious Providers, who gather "inferior" beings from all over the galaxy and pit them against each other in blood contests. This activity is the only thing that stimulates the Providers. As the three begin their involuntary training, Enterprise begins following the scant evidence their abductors left behind, trying to locate them.
January 12, 1968
17. A Piece of the Action
The Horizon visited the planet Iotia a hundred years ago, long before the Prime Directive forbid interference in pre-warp alien cultures. Beaming down to investigate the damage, Kirk, Spock and McCoy discover a culture run by mobsters! It seems that Horizon left behind a book, "Chicago Mobs of the Twenties", and the highly imitative people of Iotia patterned their society after the groups described in its pages. How can Enterprise undo the grievous harm Horizon did to this civilization?
January 19, 1968
18. The Immunity Syndrome
Spock senses the crew of Intrepid, a starship crewed solely by Vulcans, die. Enterprise investigates, and discovers a zone of darkness which conceals the hazard: an immense yet single-celled organism which drains energy from anything it encounters, as it did the Intrepid and her crew. And unless they can discover how to destroy it, Enterprise will be next. Worse, there are signs the organism has accumulated sufficient energy to reproduce...
February 2, 1968
19. A Private Little War
Kirk returns to a planet he surveyed years ago as a younger officer. There he discovers that the villagers and the hill people are now fighting, because the villagers have developed crude firearms and the idea that they should simply take anything they want from the hill people. Worse, Spock is the victim of a gunshot! Kirk and McCoy return to the surface to investigate more completely, but Enterprise must leave to avoid detection - and then a mugato bites Kirk! He must make contact with the hill people, who number among them a kind of witch doctor called a kanutu, who may be able to help. But that help comes with a price...
February 9, 1968
20. Return to Tomorrow
Enterprise responds to odd readings, which lead the crew to a planet similar to Earth, except that it is much older, and a cataclysm stripped its atmosphere away a half million years ago; it has been dead ever since. But from somewhere on that world comes a voice. Something has evidently endured 500,000 years - the last survivors of the civilization that flourished here. And all they want are the bodies of a few humans...
February 16, 1968
21. Patterns of Force
Historian and sociologist John Gill has stopped responding to transmissions. He is embedded in the Ekosian population to study it. Investigating, Kirk and Spock discover that Ekos has developed nuclear weapons - an achievement well ahead of where they should be scientifically, based on past probes. And they have modeled their society on Nazi Germany, right down to oppression of their sister planet, Zeon. It seems apparent Gill has contaminated this society, but why? And why Nazi Germany?
February 23, 1968
22. By Any Other Name
Kelvans from the Andromeda galaxy have discovered that rising radiation levels will make their galaxy uninhabitable within ten millenia. So they have dispatched generation ships of soldiers to nearby galaxies to see which of them they might conquer. Enterprise encounters such a group when her crew answers a distress call. With the Kelvans' superior technology, they may well be able to conquer the entire Milky Way galaxy!
March 1, 1968
23. The Omega Glory
Enterprise discovers her sister ship, Exeter in orbit around a planet, unresponsive. Kirk, Spock and McCoy beam aboard and discover only empty uniforms mixed with a handful of crystals. Then they find a log - the ship is infected with a deadly plague! Their only chance is to beam down to the planet's surface immediately. There, they discover heartbreaking evidence that Exeter's captain Ronald Tracy has violated the prime directive, up to and including mass murder. But he has what he believes is a good reason - and it depends on McCoy's research into a long ago bacteriological war.
March 8, 1968
24. The Ultimate Computer
Enterprise is chosen as the testbed for the revolutionary M-5 computer. The machine's inventor, Richard Daystrom, claims it can take control of a starship, freeing men for less dangerous and more rewarding work. It all depends on whether his breakthrough technology, multitronics, is as powerful and capable as he says. After a few exercises, Spock begins to wonder exactly how multitronics works - for the M-5 does not react as computers typically do.
March 15, 1968
25. Bread and Circuses
The Enterprise follows the wreckage of the S.S. Beagle to a planet where they discover an Earth-like civilization, except that Rome never fell, and rules a world much like twentieth century America. Intercepted radio transmissions suggest deeper mysteries, so Kirk, Spock and McCoy beam down to investigate, and then find themselves caught between the Roman government and a group of "sun worshippers". Proconsul Claudius wants Kirk to beam down his entire crew; the Proconsul is determined that no one will leave this world!
March 29, 1968
26. Assignment: Earth
The Enterprise has used the "light speed breakaway" technique to travel to Earth in the year 1968, to study how humans survived the desperate problems of that era. Then, they intercept a man beaming back to Earth from at least a thousand light years away, a technical feat beyond even Federation science! Who is Gary Seven, how did he get access to such advanced technology, and why has he come to Earth? He has a story, but Kirk has trouble believing it. Worse, he has trouble knowing whether he should allow Seven to pursue his agenda, or try to stop him. One of those choices is certain to destroy the future... but which?

Really hard and often boring to watch. Most stories lack a clear goal or motivation. Things just happen. At the same time its full of overacting and empty dialogue. Let me explain what I mean by comparing a Star Trek episode with a similar episode of Star Trek: The Next Generation: In episode S01E03 of the original Star Trek named "Where No Man Has Gone Before", the Enterprise happens to leave the galaxy and while flying through a nebula one of the crewmen is bestowed with supernatural powers and over the course of the episode develops extremely high intelligence and psionic powers. The crew immediatelly assume that he will become dangerous, talk about it, while he remains in the medbay and reads books at supernatural speed, can hear the thoughts of everyone on the ship, move objects around, etc. But there is no motivation to all this. He simply gets arrogant, forgets everything about being a human connection, empathy or his duties. The crew distrust him and think about killing him almost immediatelly. That itself is portayed as a shocking development. Then they decide to maroon him on the planet, where Kirk and him punch it out, another crewman weakens him and Kirk kills him and thats it. There is almost no substance, almost nothing to remember this episode. Contrast this with a similar episode in Star Trek: The Next Generation, named "The Nth Degree". The basic premise is that the crewman Barclay that we already know to be very shy and awkward around other people gains supernatural intelligence. We know his normal traits from previous episodes and its also highlighted in the beginning of the episode. Therefore, its fun to see how he changes to an intelligent and confident man who charms Diana Troy. The crew is not immediatelly afraid of him and only gets hostile towards Barclay after he takes over the ship - it makes sense. His takeover happens because the Enterprise needs to solve a problem quickly and therefore he becomes the ship's computer in an emergency situation but then wants to stay connected, because his mind would not fit into his old brain anymore. There is a motivation for this - it makes sense. So he stays connected and takes over the Enterprise and makes the Enterprise travel tens of thousands lightyears where the crew and we find out that his transformation was initiated by those aliens who use this as a way to explore other races. They make the other races come to them, because the aliens don't like to travel. Not the best motivation, but its a motivation. So after having watched ST:TNG it really stands out how most of the episodes of the original Star Trek are plain, boring, with overacted dialogues, with the obligatory fist fight and love interest of Kirk. I don't understand how anyone can like this show without a huge portion of nostalgia.

I think I am required by law to like this the most, right? Even if I am a Voyager fan? I mean, if I don't they will strip me of all my credentials. I will be kicked out of the club and banned from every comic book store across America... ... actually in 2022 that doesn't sound that bad... ... but, Yeah, you have to love Kirk, the country boy in space. The womanizing sailor. I mean, some people call him the space cowboy, some call him the gangster of love. He was just brilliant. Spock was just brilliant... and the show was a Star Trek first, it established the franchise, and.... like ALL great science fiction shows, it got canceled too soon. And then came back in movie form to establish one of the greatest franchises of all time. So, yeah, I have to like it.

Before Star Wars, this was a fan favorite for sci fi fans alike! It was campy, cheesy, entertaining, and a little bit pervy! I mean, C'mon, there were scandidly clad women in the show, even for the 60s! And don't get me started on the Starfleet women's short skirts! Probably my best highlight of the show! But yeah, the original series was the best.

The original series may be a bit hard to watch with a modern mind set, but the episodes still contain the key discussions on what it is to be human. Really the show was a great platform for modern thinking and is worth watching to understand the process that people went through to get to the modern day. Yes it is Science Fiction, but really it is Social Commentary.
