For the Phantom, there is only one 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?
