Louis XV was tired of his Polish wife. The courtiers, who notice this, organize a competition, where the goal is to find a mistress for the ruler. The nobles are betting on the best women who can distract Louis. Young and naive Louise, the eldest of the de Mailly-Nel sisters, is first in line in the king’s own bedroom. But behind her are her three younger sisters, who are also not averse to competing for the title of favorite of Louis XV. Female strength and competition, kinship and hatred, betrayal and thirst for revenge... The sisters will stop at nothing: the stakes are too high.
