At the auto show, Homer impulsively buys a snow plow and starts a business as Mr. Plow. An incredibly snowy winter sets the business rolling, making Homer a success and earning him the key to the city from Mayor Quimby. All is well until Barney sets up a rival business as the Plow King and wipes the streets with Homer. To cut out his competition, Homer calls Barney under an assumed name and dispatches the Plow King to clear a path on forbidding Widow's Peak. Barney foolishly drives up there and is caught under an avalanche. Only Homer can save him from an icy death and both men agree to work together as a team. Right at that moment, the sun bursts out and all the snow in Springfield melts into puddles, leaving them both without livelihoods.
