Dr. Anthony Edwardes, sent to replace Dr. Murchison as head of Green Manors mental hospital, is an impostor. When Murchinson calls the police, Edwardes leaves, followed by Dr. Constance Peterson, who has fallen in love with him and wants to treat his amnesia. She believes he is a medical doctor whose name is John. Skiing down a long slope, accompanied by Constance, John relives the memory of his brother being impaled on an iron fence with parallel bars, an accident for which he feels responsible. Police find the real Dr. Edwardes' dead body and John is accused of his murder.
