Upon the death of his brother, Larry Talbot returns from America to his ancestral home in Wales. He visits a gypsy camp with village girl Jenny Williams, who is attacked by Bela, a gypsy who has turned into a werewolf. Larry kills the werewolf but is bitten during the fight. Bela's mother tells him that this will cause him to become a werewolf at each full moon. Larry confesses his plight to his unbelieving father, Sir John, who then joins the villagers in a hunt for the wolf. Larry, transformed by the full moon, heads for the forest and a fateful meeting with both Sir John and Gwen. Graverobbers open the grave of the Wolfman and awake him. He doesn't like the idea of being immortal and killing people when the moon is full, so he tries to find Dr. Frankenstein, to kill him, but Frankenstein is dead and only his Monster is alive and this one wants to live, not to die like the Wolfman.
