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

McCoy gets attacked by one of the 'wild' children. One of the security guards who beamed down with the team hears him call out and is then seen very briefly to turn as if to head over to where McCoy is. Spock and Kirk saved McCoy but the guard didn't show up at all. See more »

10 November 2018 | by zitacarnoSee all my reviews

This was one of the most chilling episodes of the series. As I was watching this I got a sudden sense about those kids---and kids they were, with their fun and games and pranks, but with a strong undercurrent of fear. They were terrified of the fate that awaited them as they entered adolescence---and no matter what they did they were powerless to escape. So Kirk and Co. had to find a cure for the terminal illness, and it was Dr. McCoy who found it; he stuck his neck out and tested it on himself and discovered that it worked. And finally, when the captain, addressing the kids, said "I'm a grup---and I want to help you", they listened. So after all the trials and tribulations and anxieties all was satisfactorily resolved. A good story---and a message of hope.
