Dr. Frankenstein (Peter Cushing) returns destitute to his home village to recommence his experimental research into the reanimation of dead tissue, and stumbles upon his old monster suspended in ice. Though he revives the creature, Frankenstein must seek the help of hypnotist Zoltan (Peter Woodthorpe) to repair its mind. Zoltan then assumes control of the monster, using him to wreak havoc. But when Frankenstein tries to regain power over his creation, he becomes Zoltan's next target.
