Every year, the whole town looks forward to the Christmas tree lighting, but this year, a blizzard has struck. The snow starts to fall more and more heavily, and soon, Tractor Mac and his pals are snowed in at the barn. Farmer Bill and Sibley the horse are supposed to be on their way to the centre of town with the tree, but when they get stuck in the blizzard and it looks like the ceremony will have to be called off, Tractor Mac saves them and the whole holiday celebration.
