'South Park' is een immens succesvolle animatieserie die al sinds 1997 een hit is. In de serie over de vier basisschool jongens Stan Marsh, Kyle Broflovski, Eric Cartman en Kenny McCormick in het fictieve bergdorpje South Park wordt geen enkel taboe geschuwd. Dat de 8-jarige jongetjes er een behoorlijk onbeschaafd taalgebruik op na houden is nog het minst schokkende van 'South Park'; alles en iedereen wordt op de hak genomen! Door de simpele animatiestijl was 'South Park' altijd snel en makkelijk te maken, waardoor de makers Trey Parker en Matt Stone meteen konden inspringen op de actualiteit. In de serie wordt actueel maatschappelijk commentaar afgewisseld door absurde verhaallijnen over gigantische ballen en kutscheten. Beroemdheden komen er ook zelden ongeschonden vanaf, als zij in 'South Park' worden gepersifleerd. Zo doken Michael Jackson, Paris Hilton, Al Gore en Kanye West al in South Park op, om er maar een paar te noemen.

Schools out for summer and with Mr. Hat missing, Mr. Garrison is over the edge. The state has a ban on the sale of fireworks, and it screws up the boy's plans for a 4th of July celebration. Mr. Garrison seeks psychiatric help from Dr. Katz while Jimbo and Ned go to Mexico, in an attempt to smuggle fireworks back to the children of America.

A film festival moves to South Park, only to have a devastating effect on the sewer system. Mr. Hankey calls upon Kyle for help. The movie people interpret Kyle's pleading as a pitch and they quickly turn his story into a film starring Tom Hanks and a monkey they call "Mr. Hankey." Kyle is outraged that the filmmakers aren't hearing his pleas. Soon Chef's Salty Chocolate Balls energizes everyone.

Stan needs to build a clubhouse so he and Kyle can play "Truth or Dare" with Wendy and her friend, who has a crush on Kyle. Cartman and Kenny retaliate by building a clubhouse of their own; only theirs has hot chicks. Meanwhile, the Marshes marriage breaks up and Stan learns a valuable lesson about love and family.

Kyle, Stan and Kenny accompany Eric and his family to a Christmas celebration with the Cartman family. One of Cartman's relatives breaks out of jail for the reunion, with his cellmate, Charles Manson.

Kyle falls into a cave. Stan goes to rescue him and finds an iceman, and the two fight each other for sole credit. Dr. Mephisto discovers that the iceman has been frozen since 1996. The iceman is put on display and the fighting Kyle and Stan free him. The iceman tries to return to his family, but finds himself a man out of time. Meanwhile, the government has their own plans to use the iceman in their plot against Sweden.

The tooth fairy has visited Cartman, leaving him two dollars. He rushes to the bus stop to share his news with the others. He then unveils his latest plan. If all they all combined their lost teeth, the tooth fairy will provide them with enough cash to purchase a Sega Dreamcast. They soon find out that they are treading on someone else's territory. Now they have to work with the mobsters to keep their manhood.
