    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.

    Aired · Thu, Sep 15, 1966 · 60m

    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.

    Where No Man Has Gone Before
    Aired · Thu, Sep 22, 1966 · 60m

    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!

    The Naked Time
    Aired · Thu, Sep 29, 1966 · 60m

    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.

    The Enemy Within
    Aired · Thu, Oct 6, 1966 · 60m

    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.

    Mudd's Women
    Aired · Thu, Oct 13, 1966 · 60m

    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...

    Aired · Thu, Oct 20, 1966 · 60m

    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...

    Miri
    Aired · Thu, Oct 27, 1966 · 60m

    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.

    The Corbomite Maneuver
    Aired · Thu, Nov 10, 1966 · 60m

    Mapping star systems, Enterprise encounters an odd cube.

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.

    The Menagerie Part I
    Aired · Thu, Nov 17, 1966 · 60m

    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...

    The Menagerie Part II
    Aired · Thu, Nov 24, 1966 · 60m

    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.

    The Conscience of the King
    Aired · Thu, Dec 8, 1966 · 60m

    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.

    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.

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?

Now they have disrupted history. Christopher himself is not historically significant, but his son is. He must be returned, but how?

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.

    Aired · Thu, Feb 9, 1967 · 60m

    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?

    Aired · Thu, Mar 2, 1967 · 60m

    The Federation established a colony on Omicron Ceti III before it knew that the system's star emitted Berthold Rays, which degrade animal tissue.

    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.

    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.

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.

They arrive to find Scotty, bloody knife in hand, standing over the body of the young woman, who has been stabbed dozens of times!
