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 . . .
Leading a trek in early summer, the fine weather turns. Creeks have flooded during torrential rain and now a landslide in a deep mountain gorge separates Kirstie and her pony, Lucky, from the rest of the her group. They're trapped in Dead Man's Canyon with a herd of wild horses, one of whom has been hurt by falling rocks. Cold and alone in the gathering storm, how is Kirstie going to get help to the injured stallion?
