The desire of a wife to try the moral resistance of her man, makes her send him a love letter, coming supposed from another woman, with which she asks him to meet her in a hotel of ill repute. This meeting becomes the cause for a series of unbelievable misunderstandings resulting to a crazy hunting of the various people implicated from a room to another. Feydeau gives the monstrous image of the contemporary society reminding a mental hospital creating a hilarious comedy in quick rhythm, accuracy, sharp dialogue and frenzied action.
