People in the future live in a totalitarian society. A technician named THX 1138 lives a mundane life between work and taking a controlled consumption of drugs that the government uses to make puppets out of people. As THX is without drugs for the first time he has feelings for a woman and they start a secret relationship.

Nick and Janine live in bliss until her ex warps time to try to tear them apart by using Nick's old girlfriend. As Nick's memories and reality disappear, he must decide what he's willing to sacrifice to save -- or let go of -- everything he loves.
