Will Pride's winning streak ruin him? Wonder's Pride, the three-year-old colt of champion mare Wonder, is the newest star in Thoroughbred racing and the favorite for the biggest race of them all - the Kentucky Derby. But when Pride wins the Derby, it looks as if victory could be the worst thing that ever happened to him! Pride's owner, Clay Townsend, wants to race Pride in the strenuous three-race Triple Crown. But Pride's jockey, Ashleigh Griffen, and Ashleigh's friend Samantha McLean, who have watched Pride grow up, both believe that Wonder's Pride will suffer permanent injuries if he races too much. Can Samantha and Ashleigh stop Mr. Townsend before he races one of the greatest horses of all time - to death?
