René Artois runs a café in the small German-occupied town of Nouvion in central France. He has a relationship with a local German commander, Colonel Kurt von Strohm, whereby Rene gets essential supplies such as butter and sugar, and the Germans get to spend time with one of Rene's pretty waitresses. René isn't sure what to do when Michelle from the French Resistance tells him that his café will now be a stop on the escape route for British airmen. Additionally, he is expected to provide shelter for their forger, Roger Leclerc. As if he doesn't have enough to deal with, von Strohm steals a valuable painting from the château that the Germans have commandeered for the local headquarters, "The fallen Madonna with the Big Boobies" by van Klomp. Amid the chaos that has become René's life, they learn that Otto Flick of the Gestapo has arrived.
