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.
Unfortunately the movie Marguerite is not yet available on HBO Max.
