Melanie Graham takes Image to Florida to run in a fillies-only race as a training exercise for her high-strung horse, only to discover that her father has entered Image in the Florida Derby hoping to win some much-needed prize money.
Melanie Graham knows Image is Triple Crown material. The problem is, the filly is too smart for her own good. She's difficult to train, hates to be stabled indoors, and fights with other horses. But if Melanie is going to run Image in the Kentucky Derby, the Preakness, and the Belmont, the filly is going to have to get over herself.
For practice, Melanie takes Image to Florida to run in an easy fillies-only race. But when Melanie gets to the track, she discovers that her father has entered Image in the prestigious Florida Derby instead. He badly needs the purse money to save his failing business and he truly believes Image can win. Melanie is doubtful. Will Image rise to the challenge?
