The Scarlet and the Black

In 1943, the Nazi military occupies Rome. Pope Pius XII (John Gielgud) is approached by General Max Helm and SS Head of Police for Rome Lieutenant Colonel Herbert Kappler (Christopher Plummer). The Colonel expresses concern that escaped Allied prisoners may attempt to seek refuge in the Vatican, and requests permission to paint a white line across St. Peter's Square in order to mark the extent of Vatican sovereignty. The Pope doesn't grant his permission, but when the SS officers leave, he sees out of the window that the white line had already begun to be painted.
