Marked Cards.

Ellen Shannon, the daughter of self-made Irish politician Pat Shannon, is engaged to Ted Breslin, but because Pat began his career as a menial laborer, Ted's mother, Mrs. J. De Barth Breslin, refuses to sanction the marriage. Heartbroken, Ted takes up drinking and gambling with "Poker" LeMoyne and Don Jackson, while Ellen attends a finishing school hoping to improve herself. While trying to elude her chaperone, Ellen unwittingly dashes into a man's hotel room, and from the window, she witnesses Don and "Poker" playing cards, while Ted lies unconscious from too much drink. When the two gamblers quarrel, Don kills "Poker," but Ted is accused of the crime.
