This is a story of overcoming limitations and finding success. The story tells the tale of Tucker, an older and smaller snowplow who rescues two young kids who are trapped in the mountains after an avalanche separates them from their parents and the winter lodge. He's an older snowplow, but due to his small size and impressive determination he is able to traverse difficult terrain which newer and larger snow plows can't access. He must find the kids, Eliza and Graham, and bring them back to safety.
