The 4 season of 'Allo 'Allo! was broadcast on BBC One from samedi 7 novembre 1987 to samedi 12 décembre 1987. It consists of 6 episodes, the first one is called "Prisoners of War" and the last one "The Jet-Propelled Mother-in-Law".
In this spoof of World War II, René Artois runs a café in German-occupied France. He always seems to have his hands full: he's having affairs with most of his waitresses, he's keeping his wife happy, he's trying to please the German soldiers who frequent his café, and he's running a major underground operation for the Resistance.
