During WW2, in Rome , a trio of escaped Allied POWs find themselves in limbo as they try to avoid re-capture and reach their dispersed units. Michael Pemberton is a British Major, Fyodor Aleksandrovic Nazukov is a Soviet Sergeant and Peter Bradley is an American Lieutenant. A beautiful young Italian woman, Esperia Belli, agrees to give them shelter. She knows that despite Italy's efforts to break with Nazi Germany and join the Allies there are some Italians who are Fascist sympathizers and would gladly denounce Esperia to the German authorities. Hiding enemy soldiers or escaped POWs is punishable by death. Esperia hopes to get in contact with the Italian anti-Fascist resistance which could help the three escaped Allied POWs rejoin their respective armies. Until then, the fugitives are stuck in Esperia's attic.
