Samantha McLean has been around horses all her life, but she's never had a horse of her own. So she's overjoyed when Ashleigh Griffen and Mike Reese give her Shining, the half sister of one of the greatest race horses of all time, Ashleigh's Wonder. It's her job to turn the sickly, neglected horse into a winner, and she's got her work cut out for her. Shining is stubborn and difficult, and it looks as though she'll never race.
Then a little girl named Mandy, who cannot walk, falls in love with Shining, and the filly's training suddenly improves. But as Shining prepares for her first race, Mandy's parents make Samantha a stunning offer. Must Samantha give up the only horse she's ever owned?
