Plot details follow.
The boys play "Texans vs. Mexicans" at a sleepover at Cartman's house, a game in which the "Mexicans" (led at first by Butters, and then Kyle due to the others seeing the former as a poor leader) attempt to elude the "border patrol" (led by Cartman) and cross the border into "Texas" (Cartman's backyard). All of the boys successfully do so except for Butters, who gets lost. His absence goes unnoticed by the rest of the group. Cartman, believing that the game has been lost, becomes dejected. However, waking up from a nightmare, Cartman realizes that Butters never returned and thus the game isn't over. He wakes the rest of the group. Concerned, they begin searching for their missing friend while Cartman and his crew resume protecting the backyard.
Meanwhile, attempting to reach Cartman's house at night during a snowstorm, Butters is struck by a vehicle. Introducing himself as "Mantequilla" (Spanish for "butter") and saying he "needs to get back to his amigos at the border", the couple in the vehicle believe Butters to be a Mexican immigrant. They take him to their home and give him menial jobs to perform such as cleaning windows, washing dishes, and blowing leaves out of the yard. However, believing that Butters needs to be with his "own kind" to be happy, the couple eventually abandon Butters at an El Pollo Loco restaurant. Inside, Butters regales the staff with tales of his imaginary exploits. The staff disregards him until he gives his name as "Mantequilla", which they recognize from some flyers that the boys have posted while searching. Believing him to be someone famous, they heed his words and start to question the value of their new lives in the United States. They misinterpret Butters' desire to "cross the border" and rejoin his friends as a genuine desire to return to Mexico, and a mass exodus of Mexican immigrants soon begins. As more and more Mexicans leave, chores pile up and the Americans can't keep up with their newfound hard labor tasks creating a large gap in the economic balance and forcing the U.S. economy to fall severely.
The United States Border Patrol, now tasked with preventing Mexicans from leaving the United States, is quickly overmatched and begins recruiting volunteers. Cartman eagerly signs up and quickly displays an aptitude for stopping Mexicans, but the exodus continues. Butters, as "Mantequilla", is hailed as a hero in Mexico and is credited with instilling a sense of national pride in the Mexican people. However, he soon becomes homesick and decides he must return to South Park. While attempting to cross into the United States, Butters is spotted by border patrol agents, who are overjoyed in their belief a Mexican wants to enter the United States and make no attempt to stop him. But recognizing Butters, an enraged Cartman tries to prevent him from crossing the border. With the Border Patrol's help, Butters successfully eludes Cartman and re-enters the United States, winning the game as well as returning home. Cartman once again becomes despondent, while the rest of the gang is glad Butters is back; however, they still say he would not make a good leader. Butters proves the boys wrong by raising his arms as the voices of the Mexican people chant in response.
