Frankenstein Meets The Wolf Man (1943)

Four years after the events of The Wolf Man, grave robbers break
into the Talbot family crypt on the night of a full moon. The
thieves remove the wolfsbane buried with Larry Talbot. The full
moon shines on Larry's body, reviving and transforming him. Larry
is found by the police in Cardiff later that night, still with
the head wound thought to have killed him, and taken to a
hospital where he is treated by Dr. Mannering. During the full
moon, Larry transforms into the Wolf Man and kills a police
constable. The next morning, Larry remembers everything, and
implores Mannering to summon police before he kills again.
Inspector Owen believes Larry to be an imposter, having confirmed
reports of his death, and demands to know his real identity.
Larry becomes violently irate, then is overcome by orderlies and
bound to his bed with leather straps. Mannering also disbelieves
Larry's identity, thinking him delusional. The doctor and
detective travel to the village of Llanwelly to investigate the
Talbot tomb, only to find Larry's body gone, and one of the grave
robbers killed in the same manner as the slayings from four years
ago.


Larry transforms and kills a young girl, leading the villagers of
Vasaria to raise a mob to chase him down. Fleeing toward the
ruins of the Frankenstein castle, Larry falls through the
burned-out flooring and into the frozen cellars. Larry returns to
human form, and discovers Frankenstein's monster trapped within
ice; using a stone, Larry breaks the ice and pulls the creature
free, hoping he can show him Frankenstein's notes. The monster is
unable to locate the notes, so Larry poses as a potential buyer
of the Frankenstein estate in order to lure out Baroness Elsa
Frankenstein, Frankenstein's daughter. She refuses to assist
Larry, but the pair are invited to the "Festival of the New Wine"
by the Burgomeister. During the festival, Dr. Mannering arrives,
having followed Larry across Europe. He urges Larry to commit
himself to a mental institution before he has another spell, but
Larry believes he will ultimately escape any institution. The
monster crashes the festival and is attacked by the villagers.
Larry guides the monster onto a cart and drives him to safety.


Elsa and Mannering agree to help the villagers kill
Frankenstein's monster. The following morning, Elsa, Mannering,
and Maleva meet with Larry and the monster at the ruins. Elsa
shows Larry where Frankenstein's notes are hidden. Mannering
studies the notes and learns how to transfer life energy. Larry
asks that his life energy be transferred to the monster,
believing the laboratory can be repaired for the task. Mannering
agrees, but secretly he and Elsa plan to drain both Larry and the
monster of life.


Mannering begins the procedure, but his curiosity to see the
monster at full strength compels him to alter the process and
fully revive the monster. Horrified, Elsa attempts to stop the
machines, and as a result Larry's life is not fully transferred.
The experiment coincides on the night of a full moon, and Larry
transforms as the monster regains his strength; both escape their
restraints. The monster begins to carry Elsa away, but the Wolf
Man attacks him. Vazec, the innkeeper, suspecting Elsa,
Mannering, and Maleva of conspiring with Larry and the monster,
destroys the dam overlooking the Frankenstein estate with
dynamite, hoping to drown all five of them. Elsa escapes from the
castle with Mannering, but the Wolf Man and the monster, engaged
in their fight, are both swept away in the flood.
