Hank stages a rescue attempt when a tornado bears down on Peggy and Luanne inside a trailer park.
Hank loses his cool when he realizes Luanne washed his undergarments with hers. Shortly thereafter, a bill collector arrives at the Hill residence. Hank learns that his niece owes six months back rent for the trailer she abandoned at Shiny Pines Trailer Park. When Hank confronts Luanne, she explains that the trailer tipped over, making it uninhabitable. Anxious to rid himself of his niece, Hank uses a winch to right the toppled trailer. He then tells Peggy it is time for Luanne to leave the house. As Luanne says her emotional final goodbyes, Hank hands her his business card, explaining how it will save her ten percent on all of her propane needs. Hurt by Hank's coldness, Luanne begins crying. Furious, Peggy confronts her husband. She refers to him as a "blockhead" who is unable to express his emotions. In his own unique way, Hank tells his wife to go to hell. Shocked, Peggy climbs into her car and drives Luanne and her belongings to the trailer park. Shortly thereafter, a television reporter warns of an approaching storm capable of spawning tornadoes. When the reporter mentions that "trailer parks can be hell in a tornado," Hank grows worried.
Certain his wife is in grave danger, Hank piles emergency supplies into his truck and, accompanied by Bobby, sets off for the trailer park. Unfortunately, Hank blows a fuel filter along the way, and must fend for himself amongst panicky shoppers at the local Mega Lo Mart as he attempts to purchase a replacement. Meanwhile, Boomhauer and Dale do some tornado chasing in hopes of recording the twister on videotape. Their close encounter with the tornado sends a fifty gallon drum of pesticide flying out the back of Dale's van. Workers wearing protective suits shut down the highway until the mystery container can be identified. His progress halted by the road block, Hank loses his cool. He hits the gas pedal and continues driving.
When Hank reaches the trailer park, the tornado is ominously close. An old woman takes Bobby to a nearby shelter while Hank runs towards the trailers in search of his wife. Hank steps out of the trailer when he hears Peggy's voice calling his name. Through the swirling debris, he sees Peggy waving to him from the shelter. Suddenly, the twister descends from the sky. Hank grabs hold of a telephone pole and, fearing for his life, pours out his soul. He tells Peggy how much she means to him. The tornado passes by, sparing Hank's life but tearing off all of his clothing. An embarrassed Hank covers himself with a small potted cactus and makes his way to the shelter. With the trailer having been destroyed by the storm, Hank realizes Luanne will be living with the family indefinitely.
