Plot
The plot involves a scientist who has been discredited by his peers. He attempts to kill them off after he develops a secret formula that transforms his gardener into a murderous wolf man.
The story begins on a fog-bound moonlight night in a swamp; a wolf howls. The scene shifts to the nearby laboratory of Dr. Lorenzo Cameron (George Zucco), who draws blood from a caged wolf. Secured to a table is Dr. Cameron's simpleminded but strong gardener, Petro (Glenn Strange), who is to be the doctor's subject in an experiment. Dr. Cameron injects a serum made from a wolf's blood into the cooperative Petro, who loses consciousness, grows fur and fangs, and awakens after he has turned into a wolf man.
