1930. The memoirs of the handsome young woman who one day, at a gaming house kept in the rue de Bourgogne by M. Duquesnoy, she forms an intimacy with a rogue, the Count Du Barri, who becomes her lover, proposes to make her the instrument of his fortune, and dreams of giving her to the King Louis XV., to replace the famous Pompadour. Against all expectation, thanks to the complicity of Lebel and the Marshal de Richelieu, the ambitious dream becomes a reality. Louis XV, enticed by the indefinable charm, the gaiety, the vivacious conversation, the joyous laughter of Jeanne, falls in love with the milliner; and what the retinue takes at first for a mere passing toy changes rapidly to a veritable passion. Then, to save appearances and permit the young mistress to remain at court, she is married to Guillaume Du Barri, own brother to the rogue, and given the title of countess. The story continues from here with a series of twists and turns.
