Malcolm Shanks is a sad and lonely man, deaf, mute and living with his cruel sister and her husband, who delight in making him miserable. His only pleasure, it seems, is in making and controlling puppets. Thanks to his skill, he is offered a job as a lab assistant to Dr. Walker, who is working on ways to re-animate dead bodies by inserting electrodes at key nerve points and manipulating the bodies as if they were on strings. When the professor suddenly dies one night, Shanks gets the idea to apply their experimental results to a human body, and then to start exacting some revenge.
