In the "South Park" movie, Cartman, Kenny, Kyle, and Stan manage to get into the movie "Terrance and Philip: Asses of Fire". After seeing the movie, they begin to repeat all of the extremely foul language that was in the movie. When their parents find out about this, they force the kids to go into counseling to fix their language problem. It doesn't really work, so Kyle's mom decides that the source of the problem is Canada (the country that Terrance & Philip are from). She manages to get Terrance and Philip arrested. In return, Canada attacks the United States, and war breaks out. Terrance and Philip are scheduled to be executed. Meanwhile, Kenny (who dies early in the movie and goes to hell) overhears Satan and his lover, Saddam Hussein, talking about how Terrance and Philip's execution will be the seventh sign of the apocalypse, and goes to warn the others. The kids then organize a group to rescue Terrance and Philip before the execution.

Even if you are just a casual fan of the cartoon "South Park", you'll love the movie. Even though the first twenty or thirty minutes is filled with nothing but foul language jokes (which get old after awhile), the humor picks up pretty rapidly after that. Altogether, this movie won't appeal to people who hate the "South Park" TV show. Also, I'm sure it will offend LOTS of people. It has some very extreme content.
