From outright farce to unsubtle double entendres and mother-in-law jokes, Allo Allo! Is humour that travels easily. It mercilessly lampoons every national stereotype, so no one ever takes offence. It has crazy characters and even crazier plots, a wealth of catchphrases and, of course, Rena - the most improbable French hero since Inspector Clouseau. Series 5 of this hilarious series from widely acclaimed comedy writers Jeremy Lloyd and David Croft sees cafe owner Rena continue to aid the French Resistance in their outlandish plots to fool the Germans. With his trusty piano player at his side, Rene manages to escape a giant circular saw, fake the death of the undertaker, blast his way into the banks vault, and fit almost a million Francs down Lieutenant Grubers trousers. Can Rene obtain the plans for the German invasion in time to save everyone. Or will the overbearing love of his female collaborators force him to save himself. Find out in this explosive sitcom from the BBC.
