Theda Bara's vamping is at its most evil here. She plays the Russian Princess Petrovitch, who loves only her pearls. Her husband, the Prince (E.F. Roseman), sells state secrets to a spy to pay her exorbitant bills, and her response is to report him to the secret police. Then she runs off to Monte Carlo with her lover, Count Zerstoff (Emil deVarney), but she poisons him after he racks up a load of gambling losses.

The film tells the story of a noble but poor woman who arrives at Boston in the 17th century. There she marries an old but quite rich doctor but does not become happy.

In this lost film, Theda Bara took the role of spoiled, deceiving nymphomaniac "vixen" Elsie Drummond. She wooed Wall Street businessman Martin Stevens (A. H. Van Buren) away from his interest in her sweet sister Helen (Mary G. Martin). She continued to seek after rich men, eventually marrying young statesman Knowles Murray (Herbert Heyes) (again stolen from Helen) - but still willing to be unfaithful with Stevens who had since regained his fortune.
