On her deathbed, Renee's mother confides to her daughter the troubled history of her life. She was wealthy and she was loved alone for her riches. She was to be married; on her wedding day the bridegroom married another woman he really loved. She married her second choice of men and after two years, he left her. When Renee was born she swore an oath to the effect that her baby, Renee, would be a siren and break a heart for every tear she had shed. With this confession Renee's mother dies and the daughter takes the fulfillment of the oath upon herself. Finally she picks out Dick Northrop, the eldest of two brothers. Dane, the younger brother, admonishes Dick to beware of her. But Dick is young also. He proposes to her and is accepted. On his wedding day he receives a note which reads: "I despise you. I never intended to marry you, you fool. Renee." Dick commits suicide. Then it is that Dane swears to repay the siren in her own coin. She promises to marry him. On her wedding day she receives a note: "I despise you, I never intended to marry you, you fool. Dane." Once again Renee and Dane meet. She is at her mother's grave. He is at the grave of Dick. Over all the madness and folly which is buried in those two graves Renee appeals to Dane for forgiveness. He turns away and leaves her in the darkness with her dead.
