This upteenth film version of the life of royal courtesan Madame Du Barry stars Martine Carol in the title role. Starting out as an ambitious shopgirl, our heroine catches the eye of the even more ambitious Count du Barry (Daniel Ivernei), who in turn brings the girl to the attention of King Louis XV (Andre Luguet). Enchanted by her beauty and forthrightness, Louis takes Mme. Du Barry as his mistress, indulging her every whim. Banished from the court of Versailles by Marie Antoinette, Du Barry ultimately falls victim to the French Revolution, but she has fun while she lasts. Director Christian-Jaque wittily frames his story in the form of a magic-lantern show.
