The silent drama tells the story of a man who names himself Count Wladislaw Sergius Karamzin (von Stroheim) in order to seduce rich women and extort money from them. He has set up shop in Monte Carlo and his partners in crime (and possible lovers) are his cousins faux-Princess Vera Petchnikoff (Busch) and faux-Her Highness Olga Petchnikoff (George). Count Karamzin begins his latest scam on the unworldly wife of an American envoy, Helen Hughes (Miss Dupont), even though her husband is nearby.
