This romantic comedy is the first film pairing of Mickey Rooney and Judy Garland. He plays a young jockey who deliberately loses a race so his neer-do-well father can pay off his many debts. Afterward the owner of Pookah, the horse he rode, drops dead from heart failure. The poor jockey feels terribly guilty and wants to restore his good reputation. He then asks his father to loan the owner's grandson $1,000 of his winnings so the late owner's grandson can run a different race, but his father refuses. In desperation, the youth steals the money from his father. Unfortunately, he finds out about the theft and reports the lad to the track officials. Fortunately, throughout his ordeal his good buddy Judy sticks by his side. Occasionally she also bursts into song.
