The Crawling Hand

In NASA, the technician Steve Curan and Dr. Max Weitzberg lose contact with a spacecraft returning from the moon and they assume that the astronauts have died. Out of the blue, one of them appears in the monitor and asks to people destroy the ship, and Dr. Weitzberg pushes a button and explodes the spacecraft. Meanwhile the medical student Paul Lawrence goes to the beach with his girlfriend Donna and they find the severed arm of one astronaut. Later Paul returns to the beach and brings the arm as a sort of souvenir. The arm mysteriously comes to life and kills his landlord. Further the alien in the hand occasionally takes over his brain and he begins the prime suspect of Sheriff Townsend of being the killer in town.
