Superb skills and talent have won jockey Ben Cohen (Kurt Russell) countless trophies and honors, but as the years go by, he is slowly left behind by the endless stream of newcomers and becomes "garbage" waiting to be dealt with. The same fate is shared by the old horse Sonya, who once won countless races for her owner as a promising seed player, but after breaking her hind legs in a race due to excessive exercise intensity, she became "waste" in the eyes of her owner. Later, Sonya was given to Ben Cohen by her owner as severance pay. Ben Cohen's frustration is seen by his daughter Kyle (Dakota Fanning). In order to help her father and Sonya regain their confidence, she has made a detailed plan. First, she persuaded Ben Cohen to take good care of Sonya with her. When Sonya gradually recovered and stood up again, she tried every means to make Ben Cohen take on the seemingly impossible task of winning the "Breeders' Cup Classic".
