Carlos's Puzzle is the story of 9-year-old Carlos's family trip to a cornfield maze. Unlike Carlos, Javier, his older and more athletic brother, is not interested in the trip. However, Javier believes his athletic ability will make him better at completing a maze, so he challenges Carlos to see who will finish the maze first. Although Javier rarely recognizes Carlos's abilities, something happens inside the giant maze that gives Javier a new impression of his younger brother.
