Synopsis: The plot is a mixture of fright and sensuality as Blood Island chiefs sacrifice beautiful young virgins to "The Evil One"- a horrid creature, bred by radiation, and like a werewolf, metamorphosed from an innocent man.
Coming to this island are scientists Kent Taylor and John Ashley, along with Taylor's beautiful wife, played by the alluring Beverly Hills (Beverly Powers). Taylor and Hills search the jungle for evidence of mutated life forms as they are attacked by living vegetation and frightening animal life.
