Madame de Montespan is witty, graceful and probably the most ambitious woman at the court of Versailles. Married to the jealous Marquis, and lady-in-waiting to the powerful, she uses her position and her talent for repartee to reach her ultimate goal: Louis. 1667 will be the year when all her hard work finally pays off.
After winning the king's affections, Madame de Montespan gets a taste for power and is determined to keep it. She flatters the king, fulfilling his sexual desires, and making him the envy of all. Her influence on Louis grows and spreads to his political decisions. She becomes the de facto "Queen of Versailles". But no matter how ambitious and calculating she may be, Madame de Montespan is actually a vulnerable and terrified woman. She has seen what happens to favourites the king grows tired of. She knows that if the king's favour should wane, the court would become a merciless den of predators. She is prepared to do anything to keep the affection of Louis, with whom she is hopelessly in love: even sell her soul to the devil.
