Homer offers Marge a new Canyonero SUV after embarrassingly discovering that he bought a model marketed to women. But once in the driver's seat, Marge becomes increasingly intoxicated by the vehicle's dynamism, leading to a case of aggravated road rage.
The school is having a talent show for the teachers. The show opens with all of the teachers singing a song to the tune of "Fame." Then Groundskeeper Willie does a stand-up comedy routine, Mrs. Krabappel does a bubble dance, and Principal Skinner and Superintendent Chalmers attempt to perform "Who's on First." After these acts, Principal Skinner announces an intermission, and the audience quickly leaves. Homer has Marge drive home so he can eat some snacks he swiped from the show, and on the way home he and the kids criticize Marge's timid driving. Homer then sees Krusty the Clown driving a Canyonerosport utility vehicle, taking advantage of the SUV's size to drive wherever he wants.
Impressed with Krusty's ride, Homer gets a Canyonero the very next day, but learns to his embarrassment that the model he bought is the F-series, intended for women. He gives the vehicle to Marge, but when she uses it, she develops road rage. On a busy day racing around town, Marge is arrested and ordered to take a defensive driving course. However, she accidentally drives the SUV into the prison fence, letting loose all convicts that were (according to Chief Wiggum) only one day away from rehabilitation, and she loses her driving privileges.
Later, the police recruit Marge to use the SUV to stop a bunch of raging rhinos. They had escaped the Zoo when Homer, visiting the Zoo with Bart and Lisa, accidentally caused them to go berserk. Marge agrees to help when she sees her family in danger on the news report and succeeds in rounding up all the rhinos. When she learns that there is one missing, she sees Homer being carried off by the rhino (his belt is caught on the rhino's horn). She chases the beast to a construction site and deliberately crashes the SUV. It bursts into flames and the rhino instinctively tries to stamp out the blaze, giving the zookeepers chance to capture it. She credits her success to Stone Phillips and the whole family praises NBC. During the end credits, Homer praises Fox at gunpoint and is shot when he praises CBS.
