When a snowstorm almost hits Springfield, Homer needs to prepare for the snowstorm. First after his failed attempt of trying to get his Mr. Plow truck from Principal Skinner, Homer buys a spare Mr. Plow truck from Ned Flanders until Homer eventually gets some stuff (including a duff beer, nuclear waste, a blender and a radio), he suddenly spots a black van along way who previously destroyed Homer's old Mr. Plow truck and Homer decides to follow it. Later Homer gets himself some donuts from the Donut Truck for the snowstorm, but Homer ends up having community service. While he's on community service, Homer escorts Bames Rolfe everywhere Bames Rolfe wants to go during the upcoming dangerous storm. Soon after Homer's free to go, he finally goes back to him and he's told to pick up some grocery supplies for the snowstorm. After trying to buy some groceries at the Kwik-E-Mart, Homer tries to buy some groceries from the Grocery Store instead, but they're already loaded inside the Cube van, so Homer looks for the cube van and follows it until it picks up the groceries, and then he takes the groceries home. Then Homer realized that he forgot to plow all the snow around town, so he gets back out there to plow all the snow away before Barney reaches the point first. Then after Homer got back home, Marge wants him to pick up Grampa up and take him to The Simpsons' house for the night (because apparently the Retirement Castle would have no power by the time when the snowstorm approaches). However, Homer helps Grampa first by finding someone who stole all his hellfish treasure. According to Mr. Burns, he previously stole Grampa's hellfish treasure again, but he already traded them to the black van. So Homer gets back Grampa's hellfish treasure from the black van, and he (along with Grampa) drives away from the black van. Finally, Homer has to look for Bart and Lisa somewhere outside before the snowstorm arrives. Meanwhile, Homer helps Groundskeeper Willie prepare for the snowstorm. Will Homer be able to get everything done in time for the snowstorm?
