"Dangerous Liaisons" tells the origin story of how the Marquise de Merteuil (Alice Englert) and the Vicomte de Valmont (Nicholas Denton) meet as passionate young lovers in Paris on the eve of revolution. Driven to right the wrongs of their past, the couple rises from the slums of Paris and scales the heights of the French aristocracy, seducing and manipulating both the nobility and each other to survive.
