Plot

After gambling away his last dollar, Dan McGraw sends his motherless girl to her aunt's home, with a note imploring the woman to take care of her. Then he sells, his household effects and starts back to the gambling rooms. On the way he picks up a soiled playing card, the ace of diamonds. Confident that he will win, he plays recklessly and loses. In desperation he assaults the gambler, seizes the bankroll and escapes. Pursued by the police, he makes for his old home and secretes himself on the fire escape. The child, finding that her aunt has moved away, returns home, sees the place bare of all that constituted her little world, and begins to cry. Detectives, breaking in, discover her. The gambler, touched by her innocence, takes her to his home. Her father follows, and impelled by love, offers to restore the money. The gambler, deeply moved, kisses the child and gives her to her father. Telling McGraw that he may keep the money to make a new start, he hands the child the ace of diamonds, assuring her that it will bring her father luck this time.
