Romain has just turned 50, but he feels very good. He has a beautiful life like a publicity photo: luxury apartment, Moroccan valet, jaguar with driver, an elegant and divorced mistress, Vera. This beautiful order will be upset by two characters: Dany Lombaire, 25 years old, young man of good family, full of charm and patter, who comes to work in the advertising agency that Romain directs and will be constantly on his way; and then Eva, 22, a young girl with whom Romain falls madly in love, and who takes him into an environment that is foreign to him. All this will turn very badly for Romain who will end up marrying Vera, the only one who does not abandon her.
