Alec Dailey ran away from home at the height of the Great Depression to be a jockey, but he’s just too tall. Still, he manages to eke out a living as an exercise rider at Pimlico. Then, one day, the elves come to him and make him an offer: we give you a horse, and you ride in one of our races. Done! The horse, a beautiful black stallion, is everything Alec ever dreamed of in his own horse–except for the part where he turns out to the notorious (and recently missing) jockey, Sunny Jim, who got himself turned into a horse by the elves. (Eventually, they fall in love.)
