Bill's girlfriend Lore is an art student in Berlin. Since her professor doesn't think much of painting women, she exchanges a genuine Raphael painting in a gallery for a copy made by her. In a spectacular theft, the copy is stolen. Detective Keller suspects Bill and Lore. But Bill, who is a talented quick-change artist, eludes arrest in ever new masks.
