The children of Springfield Elementary School get stranded on a desert island on the way to a Model United Nations session. Trapped on the island with no grown-ups, the children form their own Lord of the Flies-style civilization. Meanwhile, back in Springfield, Homer starts up his own Internet company called CompuGlobalHyperMegaNet, which he sells to Bill Gates. On the island, civilization begins to break down when it appears that Milhouse has eaten their rations. During a show trial, Milhouse claims that a monster ate the food, but no one believes him. Eventually, it is revealed that a monster, actually a wild boar, did in fact eat all the food. The children, still starving, realize there's only one thing to do: kill the boar and eat it. In the end, an omniscient narrator explains that the children eventually got off the island, perhaps thanks to Moe.
