A man witnesses a murder in a secluded mansion. When he reports it, there's no evidence of the murder, or that anyone was there. Two years later he wakes up in a hospital room after a polo accident to find he's had amnesia, is now married, and living in Switzerland. Now remembering the incident he returns to England to try to solve the mystery.
