The Curious Dr. Humpp

People engaged in sex—Rachel and her boyfriend, four hippies, two lesbians, and a woman with photos of naked men—are systematically kidnapped by a hideous monster and taken away by hearse. George, a newspaper reporter, and Police Inspector Benedict investigate. A barman remembers seeing the monster at his club just before the stripper was abducted. The police sketch is published in the paper and the monster is spotted trying to buy aphrodisiacs at a pharmacy. George follows the hearse and is captured trying to break into the estate where everyone is being held.

George wakes to find himself a prisoner, too. He is befriended by Rachel, who helps him overpower Dr. Humpp\\\'s Nurse. After George has sex with the Nurse, she agrees to help him escape, but is that just a ploy? Dr. Humpp is trying to give mankind eternal life using the power of the human libido. Can he succeed?
