 Leon de Paris is a modest dog-barber in Paris. In search of more satisfaction. Thanks to the economic helps of Fanny (his terrible mother in law), he succeeds to set up in Roma a very stylish "Coiffeur pour homme". But due to this, his life with Fanny isn t funny, and more, Leon has to dissimulate homosexuality for job reasons. He decides to stop this nightmare engaging "Er Cuculo" (the cuckoo) a B-gangster to simulate a robbery. In fact the plan is to take all Fanny s money, share it among them and escape in Montecarlo. Will the strange couple succeed?
