Dr. James Brewster (Bela Lugosi) and his colleague Dr. Randall (Henry Hall) are involved in a series of scientific experiments which have caused him to transform into an ape-man. In an attempt to obtain a cure Brewster believes that it will be necessary to inject himself with recently drawn human spinal fluid. When Randall refuses to provide the fluid, Brewster and his gorilla draw spinal fluid from those whom they have murdered. Most of the movie involves a male reporter and a female reporter who snoop around trying to find out what Brewster is up to and what is happening to the people who keep vanishing without a trace. There's also another man who sometimes pops up and looks in the window. The reporters and the police don't know who he is. At the end of the movie the mystery man admits, "I'm the one who wrote this movie. It's kind of silly, isn't it?"
