The Enterprise receives an old style SOS signal and finds on arrival a planet that is virtually identical to Earth. Kirk, Spock, McCoy and Yeoman Rand beam down to the planet only to find that it is inhabited solely by children. Kirk befriends one of the older children, Miri, but they soon learn that experiments to prolong life killed all of the adults and that the children will also die when they reach puberty. They also learn that the children are in fact, very old. Soon, the landing party contracts the virus and has seven days to find a cure. Written by garykmcd

Did You Know?


This episode has a number of connections to The Andy Griffith Show (1960). The outdoor scenes are shot on the streets of the set that stood in for the town of Mayberry. Visible are the old courthouse, barber shop, feed and grain store, Walker's Drugs, bank, grocery store and the building with the small porch into which the crew runs is the old Hotel Mayberry. Michael J. Pollard, who plays Jahn, the leader of the Onlies, played Barney Fife's bumbling cousin in The Andy Griffith Show: Cousin Virgil (1962). And, when Kirk asks Spock to estimate in what time period the town seems to be, Spock responds with "1960," the year that series debuted. See more »


It is established that the children do nothing but play all day, but it has been 300 years since any non-infected adult has lived, so what do the children eat? The landing party makes frequent references to the children's food sources running out soon, but there was no technology in 1960s Earth (which this planet's civilization was identical to) that could have kept foodstuffs edible for this long, so it's unlikely children would have survived this long without starving to death or at least developing severe vitamin deficiency.

Capt. Kirk: You two will have to recreate their thinking. If you can isolate that virus, you'll be able to develop a vaccine.
Dr. McCoy: [Spock and McCoy trade incredulous looks] Is that all, Captain? We have five days, you know.

Just Who Made Their Clothes?
25 April 2014 | by (United States) – See all my reviews

Kirk and the gang encounter a group of children, living on a planet where the adults seem to have disappeared a long time ago. Upon arrival, they find a man dying in agony and don't understand the how he arrived at his condition. Investigating further, they come upon what appear to be children who act like six year olds, even though they are actually 300 years old. Dr. McCoy comes to the conclusion that there is something about the planet that causes a horrible demise when puberty is reached. Kirk tries to negotiate with the kids because they think the adults are responsible. Kirk meets Miri (Kim Darby) who develops a crush on him. Unfortunately for her, she is beginning to show symptoms similar to the dying man. She has another ally, a young man played by the very strange Michael J. Pollard who was the driver in the "Bonnie and Clyde." The kids just won't trust the crew and this presents a problem for Kirk, who begins to turn on the charm. The kids are really freaky and play violent games and won't listen to reason. Why after 300 years they have not evolved any further than they have is a real mystery. Will the condition that is affecting Miri be circumvented? That is the question.
