Robert Bidochon, very average Frenchman, and Raymonde Bidochon, born Galopin, who has nothing to envy him, got to know each other thanks to a marriage agency. After their marriage, a "cheesy" ceremony if ever there was one, they moved into a furnished apartment. And their little life goes by. Madame Bidochon takes care of everyday life, shopping, cleaning, in a word: banality. She finds that unfair. Why is she only Raymonde Bidochon when she feels, deep within herself, that she was made to be Princess Raymonde. She dreams of it. Monsieur Bidochon, he is not dreaming.
