In this sci-fi actioner, a crew of clean-up specialists dispatched to the site of a misfired rocket have no idea that they have been set up to be unwilling participants in an evil bio-geneticist's mad scheme to turn one of them into a mutant killing machine, a human prototype for a new kind of government-sponsored soldier. One man is infected, and after changing into a horrible monster, he begins killing everyone in site. But though a terrifying creature on the outside, the soldier within struggles to remember and cling to his rapidly fading humanity. The woman who owns a farm near the site of the accident does her best to save the man's life.
