An alien (Paul Birch) is teleported from another planet to earth to find blood to send back to his home planet to save his race. The problem is he has to kill his human victims to get the blood and using his mind powers he enlists the help of a nurse (Beverly Garland) and a doctor (William Roerick). This is a good Roger Corman Sci-Fi film that is well produced on a typically cheap budget. There is a good performance from Paul Birch as the superior alien who knows little about earth and Beverly Garland as the nurse who suspects her patient is not all he seems to be. This an early example of the comedy horror genre of films.
