Danny La Rue versus the Nazis, so awful it's brilliant.
Fred (La Rue) is an actor who is called up by the British Army to entertain the troops in early 1940. However, while Fred is on stage in drag, the Germans launch a surprise attack and capture everyone. Fred is told he must stay in drag otherwise he'll be shot as a spy! Unfortunately for Fred, General Brincker (Alfred Marks) takes a fancy to them!
Fred soon finds themself involved with Miss Flodden (Lally Bowers), Miss Lockhart (Frances de la Tour) who are leading a bunch of English schoolgirls trapped in France (and as this is a 1970s comedy the girls are of course saucy and oversexed), and a shot down RAF pilot (Lance Percival) whom they are hiding...
So, this is a typically British piece of whimsical nonsense, containing so many innuendoes and obvious jokes. It is terrible but incredibly funny at times. The charisma and charm of La Rue holds the film together and somehow makes it work.
