Deserted by her husband John Madison because he accuses her of having an affair, Mary Madison goes to her aunt's house to have her baby, and then loses her memory in a train wreck. John, however, hears that she has died, so he takes possession of their infant daughter. Years later, John has remarried and Mary has regained her memory, but she does not know that her daughter is still alive. When she learns how John prizes his daughter, she decides to disgrace her by having an ex-convict, who served time on a trumped-up charge, seduce her. The ex-convict and the daughter fall in love, however, and after their marriage, Mary discovers that the woman she tried to ruin is her own daughter. A less vengeful Mary then goes to John and is reconciled with him.
