A stranger in town has some big plans that could mean the end of humanity as we know it in this blend of comedy and sci-fi thrills. Nadine Story (Traci Lords) is a nurse working in the office of Dr. Rochelle (Ace Mask) when she encounters a very unusual patient -- the mysterious Mr. Johnson (Arthur Roberts), who is always dressed in black, wears dark sunglasses indoors and demands a blood transfusion. After Dr. Rochelle tests Johnson's blood, he's surprised to discover the man's body isn't producing blood in the usual manner, and Johnson hires Nadine to work in his home and give him regular transfusions. As Nadine fends off the advances of Johnson's ex-con chauffeur and go-fer Jeremy (Lenny Juliano), he discovers that people have a habit of showing up at Johnson's door but not going home again. With her help of her boyfriend, a motorcycle cop named Harry (Roger Lodge), Nadine discovers Johnson has a shocking secret -- he's an emissary from the planet Davanna, who is looking for a ready supply of human blood his people need to survive. Not Of This Earth was a remake of the 1957 film of the same name directed by Roger Corman, who served as executive producer for this version as well as distributing the picture. It was the first mainstream feature for former adult film actress Traci Lords, and features her last nude scene to date.
