One of the last pre-Star Wars science-fiction extravaganzas (based on a novel by William F. Nolan and George Clayton Johnson) takes the famed '60s maxim about not trusting anyone over thirty one step further. Set in the 23rd century, Logan's Run wakes place in a world of peace and immediate pleasure, where nobody grows old. After the age of 30, people go in for "renewal" -- meaning they are killed (although the government hides this from the population). But in this utopian paradise, some people still want to live past thirty. Known as "runners," these people are unhappy being "renew" and try to flee to a place called "Sanctuary." Secret police, called "sandmen," are employed to hunt down runners for renewal. One particular sandman, Logan Five (Michael York), is assigned to discover the truth behind Sanctuary. To do this, his life-clock is accelerated and he poses as a runner. When he suspects that renewal is more about death than life, he joins up with Jessica 6 (Jenny Agutter), a member of the underground movement, and the two flee the city hoping to find Sanctuary.
