LOGAN'S RUN

In the year of the city 2274, the remnants of human civilization live in a sealed city beneath a cluster of geodesic domes, a utopia run by computer. The citizens live a hedonistic lifestyle, but when they turn 30 must enter the "Carrousel", a public ritual that destroys their bodies, under the pretense they would be "Renewed" or reborn. Each person has embedded in their hand a "life-clock" crystal that changes color as they age, up to their "Last Day". Residents who attempt to flee the city are known as "Runners", and the team of huntsmen known as "Sandmen" are tasked to pursue and terminate them.

Sandmen Logan 5 and Francis 7 attend a Carrousel ceremony until they are called to terminate a nearby Runner. Logan finds a pendant symbol among the Runner's possessions. That evening, Logan meets with Jessica 6, a young woman wearing the same symbol.

Logan learns from the computer that the symbol is an ankh and related to a place called "Sanctuary", which the Runners appear to be seeking. There are 1,056 Runners not accounted for. The computer orders Logan to find the Sanctuary and destroy it, but must keep this mission secret from the other Sandmen. The computer changes the color of Logan's crystal to flashing red, essentially cutting his life span by four years and close to Last Day, but it does not respond when Logan questions whether he would get his years restored afterward.

Logan tells Jessica he intends to be a Runner. In the Cathedral Plaza area, after they confront some hostile youths, Logan tries to help an escaping woman Runner there, but she is killed by Francis, who now considers Logan an enemy. After unsuccessfully trying facial cosmetic surgery, and evading Francis in a sex club, Logan and Jessica meet the underground group, who direct them towards the city gate. Near the surface, they encounter and defeat Box, a robot who was originally designed to capture and freeze marine life for city food, but has since frozen any Runners who have made it that far.

Logan and Jessica escape the city, discovering that out of the computer's influence their crystals are now clear-colored. They enter the abandoned overgrown city that was once Washington, D.C. In the ruins of the United States Senate chamber, they encounter an elderly man living with many cats. The man shares what he knows about his life, including that he had biological parents. Logan realizes that Sanctuary does not physically exist, only the idea and concept to give people hope exists.

Francis has followed them; he and Logan fight until Francis is mortally wounded. Logan, Jessica and the old man head back to the dome city, but the old man stays outside, while the two re-enter through the underwater tunnels. They shout at the people to stop entering the Carrousel but no one listens to them, and the two are subsequently captured. The computer overloads after scanning Logan's brain multiple times and only getting the message "there is no Sanctuary". Logan is freed and shoots the computer; the whole facility self-destructs and falls violently, causing everyone to panic and flee. Once outside, the people gather round an artificial waterfall pool and meet the old man.

Logan and Jessica escape the city, discover the truth outside, and return to share it, while the city's controlling computer is destroyed after failing to process Logan's revelations.

The ending signifies the collapse of an artificially maintained society built on denial and control. Logan’s and Jessica’s journey exposes the fallacy of the promised 'renewal,' freeing the city's citizens from compulsory ritual and the grip of a sterile utopia. The computer's destruction represents both the literal and symbolic end of enforced ignorance and state violence.
