This riveting drama is based on the true-life story of Vatican priest Monsignor Hugh O'Flaherty (Gregory Peck), who helped allied P.O.W.s escape from Nazi-occupied Rome. O'Flaherty challenged Nazi officers and his Vatican superiors to save the lives of Jews during World War II. With German soldiers controlling Rome, O'Flaherty made a determined effort to hide and shuttle to safety as many Jews from the city as possible.
