A wild and dangerous mountain setting and a daughter who lives, breathes and sleeps horses is a recipe for trouble for ranch owner, Sandy Scott. But Kirstie is undaunted by her mother's warnings. She's at her happiest riding the trails through the tall forests and deep canyons of the Meltwater Range . . .
At a local rodeo contest, Kirstie is horrified to spot one badly-cut horse being forced back into the arena. She pleads for him to be withdrawn from the rodeo and persuades her mother to buy him for Half-Moon Ranch. But training an ex-rodeo pony isn't easy, and when Rocky throws Kirstie on a steep mountain trail, his fate hangs in the balance once more. Will Kirstie win her fight to keep and tame the problem horse?
