Renato (Ugo Tognazzi) and Albin (Michel Serrault) are happy that their son, Laurent (Rémi Laurent), is getting married. Unfortunately, the bride's father (Michel Galabru) is a die-hard conservative -- and Renato and Albin are rather conspicuously gay. To ensure that the marriage goes off without a hitch, Albin uses his skills as a drag performer to play mom for a meeting with the in-laws. But, before long, both men learn that playing it straight isn't as easy as it seems!
