After Stan, Kyle, Kenny and Cartman sneak into an R-rated movie to see Terrance and Philip, the rest of their third-grade class is quick to follow, which only outrages their parents. Upset by the effect the movie has on their innocent young minds and demanding to be heard from their small Colorado mountain town, the citizens organize a escalating boycott against Canada, where the Terrance and Philip characters come from.
