1944. Captain Billy Boyle is court-martialled on spurious charges of black market dealings. Stripped of his officer's rank and sentenced to three months' hard labour, Billy is given an opportunity: he can avoid his punishment if he goes behind enemy lines to rescue a high-value Allied soldier. A secret chamber has since been taken over by the Allies. But this 'safe house' turns out to be anything but - two downed airmen have been murdered. Billy is flown in and must solve the mystery of who is behind the murders with both the Germans and a killer hot on their heels.
