In this feature film based on the hit animated series, the third graders of South Park sneak into an R-rated film by ultra-vulgar Canadian television personalities Terrance and Phillip, and emerge with expanded vocabularies that leave their parents and teachers scandalized. When outraged Americans try to censor the film, the controversy becomes a call to war with Canada, and Terrance and Phillip end up on death row -- with only the kids left to save them.
