Fighting Youth (1925)

Dick Covington, a young society man with a quick temper and quicker fists, becomes involved in so many public scrapes that his fiancée, Jean Manley, threatens to break off their engagement if he ever fights again. Dick promises to be peaceful, but, the following day, Jean's father, Judge Manley, talks him into fighting in a charity bout to aid the milk fund. Jean breaks off the engagement, and Dick goes into training with Paddy O'Ryan. "Murdering" Mooney, Dick's opponent in the charity match, is involved in a minor automobile accident in which a car driven by Jean's younger brother backs into his car; Mooney knocks Jean's brother brutally to the ground, and Jean goes to Dick, asking to be forgiven and encouraging Dick to make hash of Mooney. On the day before the fight, Dick is kidnapped by Harold Brennty, the judge's junior partner, who hopes that, if Dick misses the match, Jean will turn from Dick to him. Dick escapes from his captors and arrives at the ring just in time for round one. Dick is being badly beaten when Jean exhorts him to do his best; he thereupon lays out the champ in short order.
