As a child, Christopher Zeller moved from Berlin with his father and sister to the English island of Jersey, where he befriended Rebecca who lived next door. When World War II begins, fascist troops occupy Jersey. As an adult, Christopher stays on the island fearlessly because of his German citizenship. Rebecca, too, decides to stay—but soon this choice turns against her. She has to register because of her Jewish background, and one day she is arrested… Christopher joins the SS and goes to work in Auschwitz, hoping to find Rebecca among the prisoners.
