The Lady Who Lied
"During a carnival in Venice, Horace Pierpont, a wealthy American (Lewis Stone), falls in love with Fay Kennion (Virginia Valli). Their romance is derailed when she goes over to his apartment and finds the vampy Fifi (Nita Naldi) there. Fay goes down to Algiers, where she marries a former sweetheart, Dr. Alan Mortimer (Edward Earle)."
