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...When Starlight's young owner, Jay, falls ill, the Scotts take the horse in. But the restless, highly strung horse doesn't settle, so Kirstie fixes a secret meeting for him and Jay. The reunion is a great success, but the parting almost breaks both their hearts. Now Starlight pines worse than before, while Jay's illness turns critical. Has Kirstie made a bad mistake?
