Follows the misadventures of four irreverent grade-schoolers in the quiet, dysfunctional town of South Park, Colorado. The curious, adventure-seeking group of 10-year-old fourth-grade boys--Stan, Kyle, Cartman, and Kenny--all join in on buffoonish adventures that sometimes evolve nothing as Stan's energetic, fun, bouncy, hyperactive, enthusiastic, free-spirited, and crazy little brother Ivan.
