Whirlpool (1950)

The wife of a psychoanalyst struggles with kleptomania and turns to hypnosis in the hope of curing it. But the man treating her is a devious quack who uses what he knows to draw her deeper into danger. When one of his former patients, now under her husband’s care, is found murdered, she is discovered at the scene with no memory of how she got there and little way to clear her name.
