Maldonne

In this thrilling mystery of mistaken identity, Jacques (Pierre Vaneck) is a piano player in a nightclub who is approached by a man he never met before. The stranger offers him a job posing as the husband of a mentally challenged woman. He will be rewarded for taking care of the woman. Since his contract has expired at the club, he readily accepts the proposition. The stranger turns out to be the valet of the woman, who other than playing with decapitated dolls, seems quite normal.
