Broadway Melody of 1938

Steve Raleigh wants to produce a show on Broadway. He finds a backer, Herman Whipple and a leading lady, Sally Lee, however his wife Caroline Whipple forces Steve to use a known star, not a newcomer. Sally purchases a horse she used to train when her parents had a farm before the depression and with two ex-vaudevillians, Sonny Ledford and Peter Trott she trains it to win a race, providing the money Steve needs for his show.
