Single white warlock seeks beautiful blond babe to join him at the altar...the sacrificial altar! When the son of Satan (Dean Stockwell) seduces a wide-eyed college student (Sandra Dee), it's a match made in hell in this "exceptional, truly engrossing film of the supernatural" (Los Angeles Times) where the romance is hot...and the terror is bone-chilling! Young Wilbur Whateley (Stockwell) has haunting eyes and an impish grin. No wonder, since his father was the devil and his mother was insane! So when Wilbur decides to start a family, he lures a cute coed (Dee) to the mountains for a weekend of demonic rites and wrongs! Now all hell is about to break loose, as their passion awakes an ancient evil determined to destroy all humanity in this sinister scare-fest of satanic seduction!. Fun Facts, Peter Fonda was originally signed to star in the film, but the role of Wilbur Whateley ultimately went to Dean Stockwell. Look for ingenue Talia Coppola ("Nurse Cora"), who, as Talia Shire, later found fame in "Rocky"
