A group of agents of the U.S. Office of Strategic Services (a forerunner of the Central Intelligence Agency) is sent to German-occupied Italy during World War II to neutralize the German-held Italian railroad system. In accomplishing the mission, most of them are killed because of an inside betrayal.
After the war, one of the survivors, Captain Webster Carey, resolves to find the traitor. Carey returns to Orta, near Milan, to determine who betrayed his team and caused the deaths of several villagers. He is surprised to learn that his former love Giulia, whom he thought dead at the hands of the Nazis, is alive and married to powerful Italian nobleman Barone Rocco de Greffi. The villagers are unfriendly, but Carey persists in his clandestine efforts to find the traitor, whom he discovers is de Greffi.
