Based on the hugely successful British television series, which ran for seven seasons, the comedy relates the adventures of a hapless cafe owner, Rene, in occupied France. He and his wife have stashed a priceless portrait stolen by the Nazis in a sausage in their cellar, where two British airmen are also hiding until the Resistance can repatriate them. Communications with London using the wireless that is disguised as a cockatoo add to the many embarrassments this intrepid proprietor endures in the company of his patrons. News that the Führer is scheduled to visit the town inspires tricksters disguised as Hitler to frequent the cafe. Meanwhile, Rene summons all the wit he can muster to save his café and his life.
