When Sam finds a home for a group of "unadoptable" mustangs, she feels like a hero. But when she promises to help care for the horses--especially the blind filly among them--she's overwhelmed with responsibilities.
Then the filly wanders off alone in a snowstorm. Will Sam be able to find her in time? Or will the Phantom be the one who saves the day?
