26 Episodes 1967 - 1968

Episode 1

Amok Time

Fri, Sep 15, 196750 mins

Lately, Spock's behavior has been increasingly and unprecedentedly erratic. When McCoy finds it to be a growing medical risk, Kirk drags the truth out of him: it is the 'blood fever', the one time in a Vulcan's life he regresses to a primitive, hormonal state of mind, setting out to mate for life. He is granted the first request for shore-leave in his entire career to go to Vulcan, asking Kirk and McCoy to join him in his equivalent of a marriage ceremony with his since-age-seven arranged fiancée, T'Pring. But, once on Vulcan, T'Pring halts the matrimony by calling the ancient challenge, whereby a champion of her choice will fight Spock for her. Surprising all, she selects Jim Kirk. He accepts after due consideration only to find, when the first of two dueling weapons are handed out, that the fight is to the death - too late to decline in front of T'Pau, the presiding top official for Spock's family and the most powerful of all Vulcan dignitaries.

The Enterprise is stopped dead in its tracks by a powerful energy force that appears in the form of a human hand. Soon, a being claiming to be Apollo orders Kirk (William Shatner) and several others down to the planet below.

Apollo's demand for unquestioned servitude, however, doesn't give the crew much choice and it becomes imperative that they locate and destroy his power supply.

The Enterprise encounters a powerful energy force that has apparently killed all human life in a solar system with over one billion inhabitants.

Return to Tomorrow

Fri, Feb 9, 196850 mins

From a planet bereft of life for half a million years, the Enterprise hears the voice of Sargon, who is able to control the ship and tells them to transport to specific coordinates which target them to a subterranean chamber. The away party consisted of Kirk, Spock, McCoy and astro-biologist Ann Mulhall; the security guards they planned to take along were prevented from de-materializing. Sargon is one of only three survivors of the planet's intelligent race - pure energy, matter without form. They tell the away party that they once started life on Earth and many other places. Suddenly Sargon possesses Kirk's body, saying he requires Spock and Ann Mulhall's bodies, too, in order to give the only other survivors of his race new life. He promises the bodies will be returned after they build superior mechanical robots as their definitive bodies, then leaves Kirk's and allows them to beam up and freely make up their minds. McCoy isn't tempted by curiosity and potential benefits, but Kirk convinces him to re-think his veto. However the human bodies need a metabolic reduction injection; the alien in Spock's body uses Vulcan mind control to make nurse Christine Chapel give Kirk, Sargon's host, an injection that would kill Sargon (and also Kirk). Sargon's wife implores Sargon to leave Kirk's body before they both die - can Kirk be revived, as his mind is still in Sargon's mind-receptacle from the planet. The aliens have more surprises in store.

They steal uniforms to enter the headquarters; but when Spock is forced to remove his helmet, his ears betray them and they are led straight to the torture chamber. After a flogging as Zeon spies, they manage to escape with a Zeon prisoner (Richard Evans), who takes them to the Zeon resistance. The resistance tests them, and plots with an Ekosian defector (Valora Noland) just to reach Gill, posing as a Nazi propaganda film crew. Once they enter inside, they discover things are not quite as they appear.

By Any Other Name

Fri, Feb 23, 196850 mins

Kirk, Spock, McCoy and a couple of red shirts beam down to the surface of a planet in answer to a fake distress call. There they are overpowered by a small group of human-looking aliens from the Andromeda galaxy, led by Rojan. Their galaxy will be uninhabitable within a few thousand years, so they intend to conquer ours, to give themselves a new home. The aliens' spacecraft had been damaged by the energy barrier around the galaxy, and they need the Enterprise to return home, enhancing its engines so that the journey will "only" take 300 years. They take over the Enterprise using their two main weapons - a paralyzing beam, and a ray that can reduce a person to a gray block of material - revival only being possible if the block is not damaged. After successfully negotiating the energy barrier, the aliens reduce all the crew into the gray blocks, with the exception of Kirk, Spock, McCoy and Scott, who must somehow overcome the aliens, revive the crew and return home.

The Ultimate Computer

Fri, Mar 8, 196850 mins

Captain Kirk replies to an urgent (yet brief) message from Commodore Enright, which only tells him to report to the nearest space station. Once there, most of the crew is removed - held in a security area, leaving only a minimal skeleton crew on-board. Commodore Bob Wesley arrives, and informs the captain he's the unwitting 'fox in the hunt;' of simulated war games to be played. The purpose? To put the so far only-rumoured-to-exist M-5 Multitronic unit - through its paces. The M-5 computer is the latest invention of the brilliant Dr. Richard Daystrom, creator of the Duotronic computer systems, which power Enterprise, and many other high-end systems. Daystrom is confidant his unit can not only take control of the starship, but do a better job than humans can. At first, the Enterprise under M-5's control easily defeats two other starships, but, quickly begins to act independently of its human masters, Daystrom has little interest in disconnecting the M-5 and treats it more like an errant child than a machine. For Kirk and the few crew members still aboard, it becomes a matter of life and death when Starfleet Command orders the Enterprise destroyed.

He assumes a classified identity to override a powerful computer, and mistakes the wrong girl, Miss Lincoln, for another agent; the computer reports both other agents he seeks are deceased in an accident. Meanwhile Kirk and Spock beam down to investigate if the alien isn't hostile, realizing the risk of changing their own past. When they get on his trail, the girl sees Spock's ears, calls the police and Seven gets away; they must first beam back aboard, then down to the base looking for Seven who overpowers security and sabotages the missile; however they get caught before Scotty locates Seven and beams him up, but he beams himself back grumbling he wasn't finished...
