The
Springfield Elementary School Model United Nations club is going on a field trip. On the bus,
Bart,
Nelson,
Ralph, and
Milhouse play a game by racing fruit down the aisle, which ends with Milhouse rolling a
grapefruit that gets stuck under the bus's brake pedal. When
Otto tries to press down on the pedal, it squirts juice into his eyes, causing him to lose control and drive the bus off a bridge into a large body of water. While swimming for help, Otto gets swept away by the current and picked up by foreign fishermen, who plan to use him for
slave labor below the deck of their ship. The students swim to a nearby desert island, where everyone falls to accusing each other before Nelson points out that the bus accident was Milhouse's fault. Bart tries to tell everyone that being stranded is fun, and imagines a lavish island lifestyle similar to
The Swiss Family Robinson, but reality sets in when the island is found to be largely barren. With no natural food, no survival skills and no adult supervision, the kids end up relying on a
cooler of snack food that Bart retrieves from the sunken bus.
Lisa quickly imposes a
rationing system on the cooler, only for the kids to awake the next morning and find that all the food has been eaten overnight. They accuse Milhouse of eating everything, while Milhouse instead tries to blame a mysterious island "monster". As they prepare to
lynch him, Lisa reminds them of why they travelled in the first place – the Model UN – and
Milhouse is allowed a trial, with Bart as a judge.
Back at home,
Homer discovers that
Ned Flanders has his own home-based
Internet business and decides he wants to start his own company. However, it turns out that Homer has no idea how to run an Internet business, does not provide any goods or services, and does not even own a computer. He is later visited by
Bill Gates and his goons, who offer to buy out Homer's company but instead destroy his office. With Milhouse on trial, Nelson has no case for the prosecution other than trying to
coerce a confession out of him, and the trial ends with Bart begrudgingly acquitting Milhouse due to insufficient evidence. However, the other kids refuse to accept Bart's verdict, and the situation descends into outright
mob rule as Milhouse, Bart and Lisa are chased into a cave. There, the children are spooked by the island's "monster", which turns out to be a
wild boar. On one of the boar's tusks is an empty bag of chips, revealing that it had eaten the snacks. Lisa realizes that there must be a nearby food source to sustain the boar and sees it licking
slime from a nearby rock. Lisa, a vegetarian, is the only one who takes to eating the slime, with the other kids killing and eating the boar instead. A narration by
James Earl Jones recounts that the kids learned to live in peace and
were rescued soon after by "oh, let's say,
Moe". ==Production==
