The Case of Becky (1921)

"Here is the strange story of a girl with two selves- two souls,-one of them good, one of them bad. And the things that one did the other knew nothing of. Can you imagine the possibilities in such a plot?"

Itinerant magician Balzamo arrives in the town where Dr. Emerson and his pretty young wife live. Smitten with Mrs. Emerson, Balzamo places her under a hypnotic spell and takes her away with him. Many years later, as she lies near death, she warns her daughter Dorothy to flee from the evil Balzamo.
