On the Mighty Mountain Road Crew, the trucks come in one size: BIG. That is, until the little snowplow joins the crew. None of the other trucks think that the little snowplow can handle the big storms, but he knows that he can do it--and just to be sure, he trains hard, pushing loads of gravel, pulling blocks of concrete, and doing plow lifts to get ready. But when a blizzard arrives, will the little snowplow's training be enough to clear the streets...

Small Walt is the smallest snow plow in the fleet and he always gets picked last, but when there is a big snowstorm in the city, he will have the chance to prove his worth.

As the town goes to sleep, a snowstorm begins, and the man who drives the snowplow goes to work, keeping the streets clear throughout the night.

Best friends Scooper and Dumper take care of their town in all kinds of weather. When a snow storm hits, they must be brave to do their jobs.
