René, Mimi and the two British airmen are still handcuffed together. They make their way to the police station, hoping that Officer Crabtree can free them. The Germans want to sell the painting of the 'Fallen Madonna'. They order René to find them a fence. A meeting is held, with Monsieur Alphonse posing as the fence and everyone else wearing paper bags on their heads. The painting is exchanged for the gold weight from the cuckoo clock. Later, the Germans decide that they'd rather have cash, so René arranges for the gold to be exchanged for forged currency. The swap is made in the church, in the confessional booth. There's a cockup and the Germans inadvertantly pass the gold on to the priest. (thetvdb.com)
