Deserted by her husband, John Madison, because he incorrectly 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 gain revenge on him by disgracing her, so she plots to have the daughter seduced by an ex-convict who served time on a trumped-up charge. The ex-convict and the daughter fall in love, however, and after their marriage, Mary finds out that the woman she tried to ruin is her own daughter. A less vengeful Mary then goes to John and is reconciled with him.
