After the plan with the submarine went awry, the British airmen have been captured by the Germans and have been locked in a cell in the château. They'll be transported to Berlin the next day. Gruber gives René the keys to the château and the cell to rescue the airmen because his name could be dropped if the airmen start talking while interrogated. Michelle thinks up a plan involving coffins to rescue the airmen and Herr Flick and von Smallhausen also think up a plan, involving disguising themselves, to get their hands on the airmen.
