Your flesh will crawl right off your bones! World War III has turned the world into a smoking cinder. The year is 1998, six years after the nuclear apocalypse, and the fallout continues to plague survivors with periodic bouts of highly toxic acid rain. A group of army deserters take refuge in a seemingly abandoned laboratory complex. They soon discover that the lab was once a top-secret government research centre gone awry. Still lurking in its corridors, a hideous genetically engineered monster emerges and a mysterious substance transforms one of them into another deadly creature! Now trapped, the four survivors must destroy the blood-thirsty beast...or die in its dripping jaws.
