Release date: 23 Jun 1976, United States
In a self-contained hedonistic society, the enforced maximum age is 30. Lifeclocks implanted in citizens hands register their ages. Once their time is out and their lifeclocks are blinking, citizens are killed in a public ritual known as Carousel, in which they hope to achieve ”renewal,” a form of rebirth. Logan 5 is a Sandman, whose job is to catch runners, people who try and escape this fate.
On the body of one of the terminated runners, Logan encounters a mysterious ankh. When he reports this object to the central computer, the computer prematurely ages his lifeclock and sends him on a mission to learn more about an underground resistance movement and a mysterious place called sanctuary. Now a runner himself, Logan gains the trust of resistance member Jessica 6 and escapes the city and the pursuing Sandmen. At the edge of the city, they meet one of the robots that maintain life within the city, and beyond that, the ruins of Washington D.C. There in the outdoors they meet an old man and come to realize the possibility of a life beyond 30.
Returning to the city to try and share their message of liberation, Logan is captured instead. Hearing that Sanctuary does not exist, the computer suffers a meltdown and explodes, ruining the city in the process. Citizens escape to meet the outside world and a new future of age and liberation.
