Gruesome horror in which two campers, Sharon (Elaine Warner) and Teddi (Ann Wilkinson) are terrorised in the deep dark woods of the California wilderness by a cannibalistic knife-wielding madman. Their boyfriends, Steve (Dean Russell) and Charlie (John Batis), take refuge in an old cave to protect themselves from the storm. There they meet the killer who tells them the story of how he walked in on his unfaithful wife and her lover. He killed them both, and gathered his two children and ran off into the forest. Unfortunately, his kids got sick and committed suicide. Since then, he has developed a taste for human flesh and will kill anybody who trespasses on his territory.
