Frankenstein Meets the Wolf Man

In Llanwelly village, two grave robbers break in the crypt of Lawrence "Larry" Stewart Talbot to steal his possessions. When they open the casket, they find the body covered with wolfbane and they are attacked by a creature. Soon Talbot awakes in Cardiff at the Queen's Hospital recovering from a surgery performed by Dr. Mannering and Inspector Owen is ready to interrogate him about recent murders. Talbot flees from the hospital and seeks out the gypsy Maleva, who knows that he is a werewolf, asking her to help him. Talbot wants to die and they travel to find Dr. Frankenstein. Talbot transforms into the werewolf and falls into the frozen catacombs of Dr. Frankenstein's castle. He finds the Monster frozen and he breaks the ice and release it. Soon Talbot discovers that Dr. Frankenstein is dead and he seeks out the daughter of Dr. Frankenstein, Baroness Elsa Frankenstein, expecting to borrow his journal that contains the secret of life and death. Meanwhile Dr. Mannering arrives in the village following the blood track left by the werewolf. When Elsa lends the diary of her father, Dr. Mannering prepares the equipment to drain power from Talbot to the Monster. But he becomes insane with the power on his hands and the experiment goes wrong.
