The Prey(1920)

Having misused funds held in his trust by investing them with his friend, Henry Lowe, Robert Reardon appeals to his future son-in-law, James Calvin, a candidate for the position of district attorney, for help. When Calvin threatens to indict Lowe for fraud if he is elected, Reardon's anger becomes so great that the engagement between Calvin and Reardon's daughter Helen is broken, resulting in Reardon's suicide. After Lowe comes into possession of a check forged by Helen's brother Jack, he uses the document to force a marriage with Helen. Treated brutally by her husband, Helen seeks Calvin's aid, but Lowe frames Calvin, now the district attorney, in a compromising situation with his ex-fiancée. Calvin is about to resign when Helen traps her husband with some marked money, causing his suicide through disgrace. Thus freed, Helen and Calvin find happiness together.
