Problemat profesora Czelawy.

Wanda, the young wife of the famous psychiatry professor Stanislaw Czelawa, has been living a nightmare for a long time - every night she is harassed by a repulsive man, twinned with her husband. Unable to bear it, the desperate woman turns for help to another psychiatrist and hypnotist, Dr. Stocki. Not quite believing her, Stocki puts her under hypnosis. Observing the Czelaw house, the man discovers the truth.
