Johnny Bromley, a rich young idler, goaded by the sneering laughter of Dot, a vamp, and by his father's open contempt, retires to a prizefighters' training camp for rehabilitation. There he meets Jenny Killian, daughter of the camp owner, and with her encouragement and love he overcomes the unpleasant memories of Dot's accusations of cowardice. When at last he is a success, he wins the hand of Jenny in marriage and his parent's forgiveness; upon meeting his former rival (The Broker) with Dot, he surprises him with a swift punch in the jaw.
