Mickey is the jockey of Thunderbolt, a prize horse ready to run in the steeple chase. Colonel Rolf Rolfe has bet his last "bottom dollar" on Thunderbolt to win. When the horse discovers a bottle of moonshine and drinks it, Mickey has to costume two stable hands as a horse and ride them in the race or he'll break the Colonel's heart.
