Jack, who is engaged to be married, is somewhat of a rounder. This is the only objectionable fault he has in the stern eyes of his prospective father-in-law. When the old man finds that Jack has been betting on the races, he forbids him the house. In the meantime, Jack, who has not abandoned his determination to win the girl, plays the races with success. The old man hears of nothing but the races at his club and he threatens to resign. Finally, his curiosity aroused, he visits a poolroom. While he is there, the poolroom is raided. The old man is captured and jailed. Through the influence of Jack, after consent has been given to the marriage, prospective father-in-law is released.
