While the Captain is sitting in the café, Herr Flick from the Gestapo is listening when René is talking to London on the wireless. He soon cracks the code surrounding the message with the plan to dig a tunnel from the mortuary to hide the British airmen. But it's soon apparent that the two airmen and Monsieur Alphonse need help with the digging, and the café staff are called in, leaving Madame Fanny and LeClerc in the café. But the Colonel and the Captain follow René, discover the tunnel, and are captured in the prisoner of war camp. (thetvdb.com)
