Cartman is set to replace Butters when Butters' parents tearfully inform the boys that Butters is missing, causing Kyle to postpone his party until next Saturday. Cartman then tells Butters that the meteor has hit, civilization has crumbled, and that the world is filled with radioactive cannibals. Butters' disappearance causes a town search party and several days later, the police announce that they will be checking ducts, wells, and bomb shelters, potentially ruining Cartman's evil plan. He then guides Butters out of the shelter, making him wear a box over his head so he cannot see that everything is really okay under the pretense of protecting him from the radiation. Cartman relocates Butters to a broken-down gas station and he locks him in an abandoned refrigerator for his protection after pretending to get bit by a radioactive cannibal. After Cartman leaves, a garbage truck comes and takes Butters to the city dump. Butters mistakes the dump for post-apocalyptic Earth, and after finding a dog, tries to build a "new civilization." A few days later, a junkyard worker stumbles across Butters and tells him the truth about everything, making Butters sadly realize that Cartman tricked him yet again.
