Gentleman Joe Palooka
The prizefighter Joe Palooka's popularity soars after his manager, Knobby Walsh, explains to reporters how "clean living" is responsible for Joe's success. The public is pleased with a hero who believes in drinking milk.
Joe's rich and unscrupulous Uncle Charlie sees a way to capitalize on Joe's good fortune. He schemes to make a land purchase, trading on Joe's good name, then blackmails Joe and Knobby once they figure out how they're being used. Joe's sweetheart Anne Howe tries to intervene as a legislative investigation of the land swindle begins, and Joe outfoxes thugs employed by Charlie to get to the hearings just in time and clear his name.
