An entire nation tunes in with rapt attention as Mr. Burns' assailant is finally revealed. At first, all signs point to Smithers, and Burns' right-hand man confesses when confronted by the police. But new evidence emerges that clears Smithers, and Homer Simpson becomes the main suspect. Based on DNA evidence and a lack of alibi, Homer is detained by police. He escapes custody, however, and rushes to the hospital, intending to get revenge on his boss for not remembering his name. At the hospital, with members of the Springfield Police Department, the Simpsons, and various townspeople standing by Burns' bed, the true shooter is revealed. Burns points into the crowd and gasps as he recalls that Maggie Simpson shot him after a tug-of-war over a lollypop. Since Maggie cannot be tried as an adult (or even a child), no charges are brought and she is free to live out her life as a cold-blooded would-be assassin.

When Springfield is chosen as the shooting location for Rainier Wolfcastle's big-screen adaptation of the popular Radioactive Man comic series, the entire town tries to take the movie's producers for every dime they've got. Children from Springfield Elementary are invited to audition for the role of Radioactive Man's sidekick, Fallout Boy. Bart tries his hardest to land the role, but the producers select Milhouse, who is initially excited about his new gig, but soon grows disenchanted with the movie-making process. After numerous production snafus and time-consuming re-shoots, Milhouse flees the set and goes into hiding. In addition to the loss of one of their stars, the financial burden of shooting in Springfield proves too much for the filmmakers, and they abandon the production altogether.

When Bart is sent home from school with head lice and Lisa loses her shoes, Marge and Homer are accused of being negligent parents and their kids are taken away by the bureaucratic do-gooders at the Child Protection Agency. As (bad) luck would have it, Bart, Lisa and Maggie are placed in the foster care of the Flanders family. While their kids must endure 5 PM bedtimes, Flanders-style nachos, and endless games of Biblical Bombardment, Homer and Marge must attend a special class for bad parents. Ned treats Bart, Lisa and especially Maggie with love and kindness, until he discovers that none of them have been baptized. After a fainting jag, Ned shores up the energy and the righteousness to baptize the kids himself. As Ned leads his new flock to the edge of the river for their baptisms, Homer and Marge, newly graduated from bad parent school, rush to the scene to stop him. Homer sees what is about to happen and dives into the river to prevent Ned from pouring Holy Water on Bart. When the Holy Water hits Homer, it burns his flesh and bubbles up. Bart, however, is saved from salvation and the Simpson family is reunited.

Bart decides to sell his soul to Milhouse for five dollars. Meanwhile, Moe transforms his dank, depressing Tavern into a family restaurant called Uncle Moe's Family Feedbag. When he stops finding Itchy & Scratchy funny and can no longer activate the automatic doors at the Kwik-E-Mart, Bart realizes that he really has lost his soul. Determined to recover it, he tracks Milhouse down at his grandmother's apartment and begs for his soul back. Milhouse tells Bart that it's too late, because he has already traded the soul for a handful of Alf Pogs. Over at the restaurant, Moe is exhausted by the constant smiling, good will and hospitality necessary to meet the demands of his new customers. Bart waits all night outside the comic book store to buy his soul back, only to learn that it has already been purchased. Depressed, Bart goes home and prays for the return of his soul. Just then, it is given back to him--by Lisa, who bought it the day before.

Lisa realizes that it's wrong to eat animals after a long petting session with a baby lamb at a local zoo. Swearing off meat turns out to be a controversial decision for Lisa, since everyone around her seems to support the eating of flesh. At school, Lisa must sit through a politically slanted pro-meat film and eat only hotdog buns for lunch; at home, she has to put up with Homer's plans for a meaty barbecue party. After fighting about her beliefs with her family, Lisa runs away to the Kwik-E-Mart, where she discovers a kindred spirit in Apu, who is not only a strict vegetarian, but a vegan as well. Lisa also meets two other vegetarians, Paul and Linda McCartney, who explain that while it's important to stick to her convictions about vegetarianism, she must also tolerate the beliefs of others. Knowing that Paul and Linda are right, Lisa makes up with Homer and they accept each other's different points of view.

In this year's blood-chilling blockbuster boo-fest, the Simpsons celebrate Halloween with three visions of terror. First, Springfield is destroyed by a band of angry, marauding billboard icons. The Lard Lad, Professor Peanut, and the Duff Cowboy escape their billboards and crush everything in sight until guest star Paul Anka saves the day with a catchy jingle. In the second segment, Groundskeeper Willie picks off the students of Springfield Elementary one-by-one. In a flashback, we learn that Willie was accidentally murdered by the kids' parents, and plans to kill the children in their dreams for revenge. It's up to Bart, Lisa, and a quick-thinking baby Maggie to fight him in dreamland. In the third segment, Homer steps into an alternate dimension, where he becomes a 3-D rendering. He finds that he's trapped in the digital world and all the attempts to save him by Professor Frink, Chief Wiggum and Ned Flanders are useless. Once again, it falls to Bart to save the day, but he fails when the digital universe implodes, sending Homer into an even scarier world: ours.

Sick of the workaday grind at the Springfield Nuclear Power Plant, Homer comes up with a scheme to gain enough weight to be classified as disabled, thereby earning the right to work from home. With a target weight of 300 pounds in mind, he eats everything in site, including Maggie's Play-Doh. Fat as a tick, Homer is granted his wish to work from home, but it's not all he thought it would be when he finds that he's too fat to stop an imminent disaster in the plant's reactor core. The only thing big enough to stop the explosion is Homer's enormous body, which he manages to wedge into an exploding tank. Having saved the plant and the town, he is rewarded for his efforts with a free liposuction courtesy of Mr. Burns.

Homer's long-lost mother returns to the Simpson family. After some initial pleasantries, Bart and Lisa suspect that something's fishy about their new grandmother. It turns out that Mother Simpson is a fugitive from the law and has spent the last quarter century in hiding. In a flashback, we learn that when Homer was a small child, his mother fell in with a band of radical hippies who planted an antibiotic bomb in the germ warfare development lab of Springfield State University. Guarding the lab at the time was a young campus security guard named Clancy Wiggum. The lab was run by a younger (but by no means young) man named Monty Burns. Ever since the antibiotic bomb attack, Burns and Wiggum have been on the lookout for Mother Simpson. Realizing that it wasn't such a good idea to emerge from the underground, Mother Simpson bids her son and his family good-bye and returns to her secret life.

Lax prison security makes it possible for Sideshow Bob to escape from prison yet again. This time, however, he's less interested in killing Bart Simpson as he is in knocking out Springfield's television stations, since he's grown to detest TV so much while in prison. Bob sneaks onto the Springfield air base on the day of the big air show, commandeers an atom bomb, and threatens to blow-up the crowd if the mayor doesn't end all TV broadcasts. When the bomb fails to explode, Bob returns to an older, more familiar plan and kidnaps Bart. That plan is also foiled and Bob returns to prison, again.

A noble spirit possesses the people of Springfield as they prepare for the town's bicentennial celebration. Always the iconoclast, Lisa discovers some new data about Jebediah Springfield, the town's legendary founder, that she feels she must share with everyone. According to Lisa's research, the saintly Jebediah was actually Hans Sprungfeld, a murderous pirate who tried to kill George Washington. Lisa confronts Hollis Hurlbut, the President of the Springfield Historical Society, with her findings, but Hurlbut sends her packing and bans her from his museum for three months. Lisa, with Homer's help, convinces Mayor Quimby to dig up the body of Jebediah Springfield to prove that he's not the same man as Sprungfeld. Quimby agrees, but when the body is exhumed, Hollis Hurlbut quickly steals the evidence so that no one believes Lisa. Later, Lisa finds out for sure that Hurlbut hid the evidence, but she allows the people of Springfield to go on celebrating Jebediah anyway, since the great man's legacy is more important than the actual facts of his life.

Mr. Burns' assistant, Waylon Smithers, nearly works himself into a nervous breakdown and is forced to go on a vacation. Fearing that whoever fills in for him in his absence might replace him permanently, Smithers places Homer Simpson in the job, figuring that there's no way the plant's worst employee could possibly be a threat. Homer approaches the job with enthusiasm, but finds that much of his day is taken up with being insulted by Mr. Burns. Finally, one day Homer snaps and punches Burns square in the face. To everyone's surprise, the punch actually whacks some decency and humility into Burns. When Smithers returns from his vacation, he finds that his worst fear has come true: Burns no longer needs him.
