Mindwarp is a 1992 post-apocalyptic science fiction film, starring Bruce Campbell, Angus Scrimm, Marta Martin, Elizabeth Kent, and Wendy Sandow. The story takes place in the year 2037, after the loss of the ozone layer has left most of the planet a desolate wasteland scattered with highly radioactive "Death Zones", except for several areas that still flourish. Much of the human population has been reduced to Crawlers, mutated cannibalistic underground dwellers who have lost their intelligence and speak only in grunts and mine garbage dumps. Outworlders are un-mutated humans who live in the Death Zones. A few humans are Dreamers, who live in Inworld, a sealed biosphere maintained by the central Infinisynth computer. They spend all their time plugged in via implants in their necks, living through virtual reality fantasies.
