Based on J. P. Gallagher's book "The Scarlet Pimpernel of the Vatican," this adventure film tells the story of a real-life hero. Monsignor Hugh 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 Jewish people in the city as possible. But his task wasn't easy because a villainous German colonel suspected just what the priest was up to.
