Little Johnny Jones is a jockey who is in love with his all-American sweetheart, Mary Baker, and also his career as the rider of thoroughbred horses. But he almost loses both when he is tricked by a showgirl, Vivian Dale. His story of vindication swings from the racetracks of America to England and the historical National Derby, with plenty of red-white-and-blue bunting waving behind the little patriot.
