Dangerous Liaisons (1988)

Set in France around 1760, the Marquise de Merteuil needs a favour from her ex-lover, Vicomte de Valmont. One of the Marquise de Merteuil's ex-lovers, Gercourt, is betrothed to a young, virtuous, woman called Cecile de Volanges. The Marquise would like Valmont to seduce Cecile before her wedding day, thus humiliating Gercourt. Meanwhile, Valmont has a conquest of his own in mind: Madame de Tourvel, a beautiful, married, and God fearing woman. The Marquise doesn't think that Valmont can seduce Mme de Tourvel. She tells him that if he can provide written proof of a sexual encounter with Mme de Tourvel, she will offer him a reward: one last night with her. Valmont, however, will find himself falling in love with Mme de Tourvel, and facing the deadly jealousy of the Marquise de Merteuil. All along, Cecile de Volanges is used as a pawn in this game of sexual conquest and scorned love.
