Josephine, a seemingly happily married mother, comforts her friend who has just found out that her husband is cheating on her with her own story: raised in an infamous dive and taught to steal money from her customers, one night she meets a well-known novelist and his wife who are “slumming” and who give her a sum of money in order for her to leave her surroundings, but her guardian takes it from her. She is eventually sent to a reformatory but escapes and finds the novelist, now divorced. She determines to once and for all escape the life she’s in and offers herself to the novelist in exchange for a promise of marriage. Complications ensue. When the place is raided, Jo is sent to a reformatory, but she later escapes. So that she will not have to return to the reformatory, Harrison marries her “in name only,” with the idea that after a few months they will divorce. When Nina, now unhappily married, starts pursuing Harrison, his friend Huntley McMerton helps Jo make Harrison jealous, whereupon he declares his love. Jo suggests that her friend should act similarly.
