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

When preparing to go to Yonada, Kirk enters the transporter but his right foot is off the disk on the floor when the camera cuts and we hear the transporter activation sound. When he arrives he is fully intact, foot and all. However, this is a common practice, as they are able to transport large crates of equipment which is much bigger than an individual pad, which shows one does not have to be exactly on the pad for transport.

The Oracle of the People: You have listened to the words of the non-believers.
Natira: Yes, I have listened.
The Oracle of the People: That was the first transgression. You felt the pain of warning?
Natira: Yes, I did.
The Oracle of the People: Why did you listen further?
Natira: They said they spoke the truth.
The Oracle of the People: THEIR truth.
Natira: Is truth not truth for all?
The Oracle of the People: The truth of Yonada is YOUR truth. There can be no other for you.

User Reviews

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 ?
