Dr. Victor Frankenstein, an ambitious young scientist, is consumed by a fanatic desire to create a living being. He fashions an eight-foot creature and succeeds in animating him but, horrified by his visage, perceives his creation to be a monster and frightens him away. The monster, wandering in search of human companionship, is spurned and repulsed by all he approaches and learns to hate and to kill. He confronts his maker with a terrible choice: unless Frankenstein creates for him a mate, he will go on a rampage of destruction.
