The Enterprise in attacked by a missile, launched from an asteroid on an independent collision course with highly populated planet, Darren 5, in 396 days, which has simple atomic power and an internal atmosphere, but no inhabitants. McCoy has found he's the only unhealthy crew member: only one year of life left. Kirk, Spock, and McCoy beam down to the asteroid surface but are suddenly overpowered by sword-bearing men, commanded by high-priestess Natira who makes them kneel before a worshiped oracle, which smites them down electrically. They are given a medicine by an old servant who suffers pain twitches while telling them "things are not as they teach us", and that he once climbed the mountain and touched the sky. He then dies. The earthly visitors are now offered hospitality. The high-priestess asks McCoy to stay as her mate and explains the people is on its way to a new, green world, 'soon' according to the oracle. Kirk and Spock discover the oracle was build by the alien Fabrini ... Written by KGF Vissers

The entrance set used for the entrance portal to the "underground" section of the Yonada world-ship was used again in Star Trek: The Original Series: The Cloud Minders (1969). See more »


When briefing Captain Kirk, Mr. Spock says that the asteroid is "200 miles in diameter", nowhere near the size of a planet so it can't have enough natural gravity for humans to walk normally as depicted. The more so as the object is hollow. To the same token, the gravity force would be more or less centered in it and there would be no normal "top" and "bottom" as shown. But it is highly likely there is an artificial gravity system aboard. See more »


Mr. Spock: Incredible as it may seem, these people have no idea they're living on a spaceship.
Captain James T. Kirk: I wonder how many generations have lived out their lives, and... been buried here, without ever knowing that their world is hollow?

A good political story.
25 July 2019 | by rudge49See all my reviews

Yes ! Remember this was produced in 1968. The Soviets sent troops into Czechoslovakia to crush the Prague Spring, China was consumed by the Cultural Revolution, the world was a very dangerous place. Throughout the centuries tyrants of every stripe and persuasion have tried to control the information their subjects receive and blame so many of their problems and failures on outsiders with malicious intent. A self contained world where people have few if any memories of the "Good Old Days" and no way to contradict what they are told by their rulers, and face severe punishments if they rebel. Truth is what the rulers-or ruler-will decide on. It does recycle the controlling computer idea from "Return of the Archons"-I wonder if those who built the Oracle saw Landru's plans ? The Prime Directive ? As Kirk told Spock in "Return of the Archons " "That refers to a living breathing society ! Do you think this is ?
