Returning from the planet Venus, an errant NASA spacecraft crashes into the ocean, spilling its radioactive cargo. Enveloped by a radioactive mass, a rabid weasel is transformed into a gigantic killer mutant. Prowling the countryside, the huge weasel kills and devours victims. The creature is captured by a disturbed scientist who plans to use its regenerative blood to amass an army of similar monsters, enabling him to conquer the Earth.

A series of horrible murders prompts a massive police investigation. Inspector James Cameron, a two-fisted roughneck with his own philosophy on handling crime, heads the investigation. A group of lepers living in the Long Island wastelands have created a terror network, killing and feeding off the flesh of innocent victims. Their leader has mutated into an invulnerable monster; he intends to propagate and strengthen his stronghold. Aided by his son Jack and a couple of motorcycle freaks, food is supplied to the clan via murder. As the authorities close in on the cannibal killers, an all-out bloodbath ensues.
