Gregory Peck and Christopher Plummer give outstanding performances as Monsr. Hugh O'Flaherty(Peck) and SS Col. Herbert Kapler(Plummer). The story follows Peck as a Vatican official trying to save Italian Jews and Allied POW's escaped from the hands of the German SS. Plummer's portrayal of Col. Kapler is both chilling and frightening, especially when he personally executes a Catholic priest who was caught helping the Resistance. Peck's portrayal of Father O'Flaherty is very moving to watch. The intelligence and compassion of this man truly shows through and reveals how deserving Father O'Flaherty was of the awards and decorations he received from the Allies after the war. The ending is of the movie is surprising. A plus - the movie was filmed in Rome where the actual events took place. A truly classic movie.
