When he goes to war, Theodore Pendergast is a snob. When he returns from the trenches of France, he is a democrat whose best friend is Butch McGuire, an ex-prizefighter and regular guy. Ted (as he is now called) takes Butch home with him to meet his father, and the old gentleman immediately has Ted committed to a sanitarium. Ted escapes and goes to live with Butch, whose sister, Molly, runs a beanery in a rough section of town. Ted is accepted by all of Butch's friends except Kid Lowry, a prizefighter who finally goads Ted into a grudge match. Before the fight takes place, however, the elder Pendergast has Ted kidnapped and placed in a padded cell. Ted again escapes and arrives in time for his match with Lowry. Ted is losing the fight when Molly appears and urges him on. The police raid the place, and Ted escapes with Lowry, whom he trounces after they have eluded the cops. Ted proposes to Molly, insuring a marriage that pleases the elder Pendergast, who has belatedly come to appreciate the loyalty that Molly and Butch have shown his son.
