Near the end of World War II, a secret American raid on an enemy transportation hub goes very wrong when a turncoat warns the enemy. Led by Capt. Webster Carey, the mission causes the deaths of many bystanders -- among them, Carey believes, his Italian girlfriend, Giulia de Graffi. Back home, Carey stumbles across evidence that might uncover the identity of the informant. But, when he returns to Italy to get even, Carey is stunned by what he finds.
