In order to inherit twenty million francs, brother and sister Peppo and Gorgone destroy the death certificates of a brother and sister who died in Calcutta, and assume their identities. They hire a law firm in Paris, where Gorgone meets the Count de Moray, a wealthy diplomat who just returned from India. Gorgone attempts to ensnare him. When she learns that the count's wife, Countess de Moray, has pledged a necklace to a jeweler for a loan to pay her mother's illegitimate son, gambler Robert Burel, to keep his identity secret, Gorgone convinces the count that his wife has a lover and arranges for him to see her pay Robert and embrace him. Count de Moray 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, but agrees to marry Peppo in order to save her father from financial ruin. The countess gets her mother to confess, and Drake proves that Peppo and Gorgone are imposters. The countess forgives her husband, Peppo takes poison, and Gorgone accidentally stabs herself to death trying to kill the count.
