After being betrayed and then cast off by attorney Phidias Trent, Rita Castle places her infant daughter Alicia in a convent. A short time later, Rita marries Ralph Christie, a widower and the father of a little boy, Dick. When Christie learns of Rita's past, however, he divorces her. Years later, Trent, now happily married, is nominated for district attorney, and Rita, who has become a political lobbyist, decides that it is time to extract her revenge and threatens to expose Trent. Trent's campaign manager, Hal Clement, in turn threatens to reveal Rita's former life to Alicia, who has met and fallen in love with Dick. Clement then assaults Alicia, and Rita, returning home, shoots and kills him. It is the duty of Trent, the new district attorney, to prosecute Rita. She informs him that her daughter is also his child.
