Tangled Lives (1917)

After squandering his entire estate, Roy Schuyler is forced by his creditors to marry wealthy Laura Reid. Her half-sister Ann tries to warn her of Roy's motives, but is kidnapped by Roy and incarcerated in an asylum before she can. Roy then tries to force Laura to sign a document which would accord him control of her estate. When she refuses, Roy, with the aid of Dassori, a traitor from Italy, brings Ann and Laura together. Ann dies and Laura, who closely resembles her, is placed in the asylum in her stead. Laura is finally saved when her cousin Marion bribes a nurse to allow her to escape and Dassori, with moments to live, confesses his part in the crime, thus establishing Laura's true identity. Justice is then served when Roy is driven to his death by his tortured conscience.
