The Great White Way (1924)

Jack Murray, a press agent, tries to make popular his two clients--Joe Cain, a prizefighter, and Mabel Vandergrift, a follies dancer--by linking their names romantically. His plan succeeds when they actually fall in love. However, Morton, the jealous owner of the show, threatens to close it if Mabel does not renounce Joe. To save the show and his own reputation, Joe buys out Morton by agreeing to fight the English boxing champion. All ends well when Joe wins the title. The show is saved, and Mabel and Joe return to the West with Joe's father.
