The kids go to an educational field trip, which they don't like, even, but especially, Stan and Wendy, and also especially Cartman, who forces Butters to sneak out to Super Phun Thyme. They left just in time, however, as trigger happy thieves break in. As Stan, Wendy, Kyle and Jimmy try to get the dedicated employees to act like it's 2008 instead of 1864 and call the police, and subsequently hide, can Butters force Cartman to return in time? And will Stan have to risk his life, and dignity, to save the class, who have been taken hostage?
