Experiment #331

A scientist working in a top-secret government weapons technology research becomes so disillusioned that he destroys his latest creation: an ultra-sophisticated flying attack laser. Soon, terrorists who want him to re-create the invention kidnap him. A shady government contact recruits two veteran Special Forces operatives Ron Morrell and John Slade who soon find themselves in a frantic race against the clock to rescue the scientist and keep his deadly knowledge a secret.

After a lengthy space mission, two astronauts (Steve Barkett and Larry Latham) return to an Earth transformed by nuclear war. As renegade gangs and mutants rule Los Angeles, the astronauts join two pretty women and a couple of kids in a growing resistance movement. This sci-fi adventure follows the men as they battle bell-bottomed biker leader Cutter and his brutal gang.
