Sam Hell (Roddy Piper) is a muscle-bound combination of wise guy cool and deadly force. It's up to Hell and the armed and dangerous beauty Spangle (Sandahl Bergman) to brave the barren wasteland once known as Earth and ruled by slimy, green overgrown amphibians. Their mission: to perpetuate the race by impregnating as many fertile women as possible. Humanity's last hope for survival lies in the abilities of a beauty and a beast!
