Once hounded from his castle for creating a monstrous living creature, Baron Frankenstein (Peter Cushing) returns to his ancestral home in Karlstaad, determined to continue his experiments into the creation of life. High in the mountains, Frankenstein and his faithful assistant, Hans, stumble on the body of the creature, perfectly preserved in ice. He is brought back to life, but Frankenstein is forced to employ a hypnotist, Zoltan, to complete the process. Unbeknown to Frankenstein, Zoltan now controls the creature and has plans to use him to rob and pillage the local villages. Can Frankenstein break Zoltan's hypnotic spell, or will Zoltan induce the creature to destroy its creator?
