Updated adaptation of Choderlos de Laclos' classic 18th Century tale of seduction, betrayal and revenge set in the modern 1960s world of Parisian high society. The beautiful Madame de Merteuil seeks vengeance against her ex-lover Gercourt when he becomes engaged to her young goddaughter, Cécile. Merteuil turns to her ex-lover/partner-in-crime, Valmont, famous for his reputation as a Don Juan, to seduce Cécile and emotionally destroy her. While on his mission, Valmont gets sidetracked when he goes to visit his aunt and falls for Madame Tourvel, a virtuous, married woman who knows of his womanizing ways, but that only makes the challenge more exciting to Valmont. Together, Madame de Merteuil and Valmont make a dangerous team and they will stop at nothing when it comes to matters of the heart.
