A Wife's Sacrifice (1916)

Brother and sister Peppo and Gorgone destroy the death certificates of a brother and sister named Palmieri who died in Calcutta, and assume their identities so they can inherit 20 million francs. They hire a law firm in Paris, where Gorgone meets the Count De Moray, a wealthy diplomat who just returned from India, and attempts to ensnare him. When the count's wife pledges a necklace to a jeweler for a loan to pay her mother's illegitimate son, gambler Robert Burel, to keep his identity secret, Peppo informs Gorgone, who convinces the count that his wife has a lover. When Gorgone pays Robert, the count sees them embrace. He shoots Robert, divorces the countess and marries Gorgone. Later, the count's daughter Pauline returns from India with her sweetheart, Elliott Drake of the Italian consulate. After Pauline agrees to marry Peppo to save her father from financial ruin, the countess gets her mother to confess, and Drake proves that Peppo and Gorgone are impostors. The countess forgives her husband, Peppo takes poison, and Gorgone accidentally stabs herself to death trying to kill the count.
