Plot

In 1947 England, plastic surgeon Dr. Rossiter is wanted by police after performing a botched operation on socialite Evelyn Morley. However, believing himself to have brilliant abilities as a surgeon, he and his assistants, Martin and Angela, evade capture and escape to France. To avoid capture, Rossiter changes his name to Dr. Schüler. Schüler sees a girl scarred in the recent war, Nicole, and befriends her father, a circus owner named Vanet. Schüler performs a surgical procedure on Nicole to restore her face. Schüler then suggests to Vanet that they become partners; Vanet will sign the circus over to Schüler, who will pay all the bills, but they will have a private document to show it still belongs to Vanet. Vanet realises that the doctor is on the run from something or someone, and wants a place to hide out in, but is glad to repay him in any way he can, and also hopes to save his circus. Drunk from his celebration, Vanet tries to dance with the bear that is part of his act, but drops a bottle which injures the animal, who starts to maul him. He screams instructions to the surgeon about how to control the bear; at first Schüler runs to help, then realises his opportunity, and leaves Vanet to die. With the assistance of Martin and Angela, Schüler begins to recruit performers, seeking out lowly and disfigured criminals whom he offers to transform with surgery should they join him. In Paris, he encounters prostitute Elissa Caro robbing and killing a man in an alleyway. Schüler offers to transform Elissa's face—which is marked by a large scar—and provide her a new identity as a performer in his circus. She reluctantly agrees.
