For the Phantom, there is only girl. For Sam, there is only one horse.
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?
