Goat Getter (1925)

While making a series of boxing exhibitions, "Lightning" Bradley, the lightweight champion, is matched with Billy Morris in a small western town. Bradley knocks Billy out, and Billy, looking for a revenge rematch, follows the champ from town to town, taunting him and "getting his goat." Billy follows Bradley to Hollywood, where the champ is making a picture. Billy gets a chance to box Bradley before the cameras in what is expected to be a set-up, and knocks him out. Bradley's manager tries to stop the story from getting into the newspapers, but Billy outraces his thugs and breaks the news. He also wins Virginia Avery, the star of the film.
