The Lady and the Monster is a 1944 American science fiction horror film directed by George Sherman, and starring Vera Ralston, Richard Arlen, and Erich von Stroheim.

[2] Professor Franz Mueller is the proud owner of his self-built advanced scientific laboratory set in an old castle in the middle of the Arizona desert.

Mueller is assisted in his attempts to prove his theory by another scientist, Patrick Cory, and his young Czechoslovakian-American ward, Janice Farrell.

They are also able to determine, from searching through the dead man's clothes, that the body belongs to an infamous investment banker named William H. Donovan.

In the morning the wife of the late banker, Mrs. Chloe Donovan, arrives with the family lawyer, Eugene Fulton, to transport the remains from the castle.

Not believing that Mueller is entirely truthful, Fulton remains in the nearby area to further investigate the last hours of Donovan's life before he was declared dead.

Completely under the influence of the brain, Cory leaves for Los Angeles Federal Prison and manages to withdraw cash from one of Donovan's hidden accounts.

In a sting of jealousy, Mueller's housekeeper and mistress-wannabe feeds sedatives to the brain and it loses its control over Cory, who regains his consciousness.
