(The complete plot for this South Park Episode)
Our boys and their parents go to a Native American reservation where is a casino. Here, Gerald (Kyle's father) ends up losing the house betting on blackjack. He tries to make it look as if it is his son Kyle's fault after he stated he wanted to leave the casino by making it sound like he wanted to leave South Park. It turns out he's not the only one. The entire town is bought out by the Native Americans, who plan to tear it down so that they can build a superhighway connecting their casino to Denver, Colorado. The entire town is forced to leave their homes, and have no way to buy back their town.The boys meet with some of the other kids in town to come up with an idea. An unfamiliar new boy named Alex points out that they have to save the town. The boys advise their parents to get all the money they have, and then go bet it at the casino. If they win a round of roulette, they would have enough money to buy back the town, plus US$50,000. They win but, as expected from avid gamblers, bet all their winnings again and lose. When they are selling their homes, Stan, Kyle, Cartman, and Kenny try to get them to stand up for the town, and are backed up by Alex. Initially the adults say they will move to Middle Park instead. The boys testify "until the Native Americans come to take Middle Park too." While the adults remain naive, the four main characters run outside and stand in front of the Native Americans' bulldozers, blocking their path. The townspeople soon join the boys protesting the bulldozers, whilst singing "Love Is a Battlefield" by Pat Benatar. The casino's owner, Chief Runs With Premise, plots another way to get rid of the townspeople.
The Chief decides to give blankets to the townspeople, after infecting the blankets with SARS by rubbing them with naked Chinese men. The whole town gets sick, except for Stan, and his father tells him that if he does not find a way to cure SARS, only 98% of the town would be left. At the same time, however, the casino owner's son, Premise Running Thin, gets infected with SARS accidentally because he had shared a drink with one of the Chinese men, and none of the Native Americans' herbs are able to cure him. The owner decides to take out his anger on the townspeople with Operation Shock and awe. Stan meanwhile goes to a wise old man in a trailer in another town, who gives him an "inward journey" brought on by sniffing paint thinner. He discovers the middle-class white man's way to cure sickness using Campbell's chicken noodle soup, DayQuil, and Sprite. The people of South Park all recover.
The casino chief arrives and is shocked to find the people are healthy and not half-dead. He begs them for the cure to SARS for his son, and they give it in exchange for their town back. Alex gives the lesson that South Park is really more than a town, but a community of people. Then Stan and Kyle, visibly irritated at the new kid's presence, question him on who he is, telling him to go away.
