Paris in the 1920s. Marguerite Dumont is a wealthy woman with a passion for music and the opera. For years, she has performed regularly for a circle of guests. But Marguerite sings tragically out of tune and no one has ever told her. Her husband and her close friends have always encouraged her in her illusions. Things become very complicated the day she gets it into her head to perform in front of a genuine public, at the Opera.

A struggling writer finds a shortcut to fame, but a blackmailer threatens to ruin his perfect life.

How to become a man when your mother and your closed circle have decided otherwise? This is the challenge Guillaume took up. The film recounts Guillaume’s tragicomic battle from the young age of eight, as he adopts the role of a girl then of a homosexual… until, aged 30, he meets the woman who, after his mother, will become the other woman in his life. Beyond this story of a heterosexual coming-out, the film tells the tale of an actor who never stopped loving women, maybe even a little too much.
