Based on a play by a German-Jewish exile in Moscow, Friedrich Wolf, and directed by an Austrian-Jewish exile in Moscow, Herbert Rappaport, the film tells with the story of an apolitical humanitarian Jewish doctor and his politically-aware, fascism-resisting son, an intern, as their lives become entangled with the Nazis’ rise to power in 1930s Germany, where they live and practice.
