Not of This Earth

Nadine Story (Traci Lords) is a nurse working in the office of Dr. Rochelle (Ace Mask). She encounters an unusual patient Mr. Johnson (Arthur Roberts), who is always dressed in black, wears dark sunglasses 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. With the help of her boyfriend Harry (Roger Lodge), she soon discovers that Johnson is an emissary from the planet Davanna, who is looking for a ready supply of human blood his people need to survive.
