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.
