In a post-apocalyptic future, Earth is taken by radioactivity and the ozone depletion causes high temperatures. A nomad wanders in the desert and finds an android head and hand. He brings the parts to sell to the seller Alvy, but the soldier Moses "Mo" buys the head to give to his girlfriend Jill, who is an artist that makes sculptures. Mo and his friend Shades go to New York to meet Jill and she uses the head in her sculpture. Meanwhile Alvy researches the origin of the head and discovers that it belongs to the dangerous project Mark 13 that was provided with artificial intelligence and programmed to rebuild itself, but deactivated by the authorities because of its vulnerability to the rain. He summons Mo to tell his discovery and Jill is left alone with the lethal machine that is rebuilding itself with the parts she uses in her sculptures.
