Jet is a border collie puppy tired of feeling hungry and lonely. He's tired of the collar that yanks at his neck and the leash that makes things worse. When his owners move away and leave him tied up in the backyard, it seems like Jet is running out of time. When Jet is saved by a home inspector, he's taken to the Sterling Center, where he shows all the classic signs of a great rescue dog, but he's terrified of the leash. When a plane goes down in the wilderness and a snowstorm is moving in, will Jet be able to overcome his fear in time to become a hero?
