Homer and Marge go to the kids school for Parent-Teacher night with Marge reluctantly going to Bart's class. Although Lisa is given a good review by Miss Hoover and Homer is even applauded as a father, by stark contrast Mrs. Krabappel is appalled at Bart's behavior and forces Marge to write on the blackboard. She tells both parents that if Bart doesn't change soon then he will look forward to nothing but a wasted life (i.e. a male stripper), but if the parents act now he could be the Chief Justice of the Supreme Court. On the car ride home, Marge becomes concerned about Bart's attitude and how Homer rarely punishes him. When they get home, they discover Bart has broken Grampa's dentures and send him to bed without supper. Bart seems to change his ways until Homer sneaks him some dinner. The next day, Lisa learns about the upcoming Itchy and Scratchy movie and she and Bart immediately get tickets.
Later, Marge and Lisa go shopping, during which Bart causes trouble at home and tricks Homer into not punishing him. When the girls return Marge learns of what's happened and orders Homer to punish Bart the next time he misbehaves. When Bart is asked to watch Maggie and doesn't (leading her to take the family car on a joyride and crash into prison, freeing several convicts), Homer punishes him by tearing up his Itchy and Scratchy movie ticket, forbidding him from seeing the movie for the rest of his life. Bart becomes depressed that he can't see the movie, as everyone around him raves about it. After two months, Marge and Lisa beg Homer to let Bart see the movie due to Bart still being upset. Marge feels the punishment has made Bart learn his lesson, but Homer still refuses to ever let Bart go. Bart even sneaks over to the Aztec theater to buy a ticket, but the ticket sellers have been ordered not to sell to him.
Eight months (and 9 Academy Awards) later, the movie officially leaves the theatres. Bart sadly admits that Homer has won, but Homer explains they 'both won,' and that by using this punishment, Bart is in no doubt headed for a better life. The episode then flashes forward to forty years in the future, where Bart (now he actually is Chief Justice of the Supreme Court) and Homer walk down a street, and see that a theater has re-released "The Itchy & Scratchy Movie." Homer explains that he feels Bart has learned his lesson, and the two enter the theatre and watch the movie happily together.
