Set amid the elegant châteaux of Belle époque France and the closely guarded world of nineteenth-century Persian women, Courtesan unfolds with the breathtaking cinematic sweep and stunning visual grandeur of an epic film. At its heart are three unforgettable women: Madame Gabrielle, the courtesan whose fateful liaison with the shah of Persia reverberates in the lives of her daughter, Françoise, and her rebellious and brave granddaughter, Simone, whose journey plunges her into the cutthroat diamond trade, where the secrets of an ancient culture may hold the truth she desperately seeks.
