Chet is average in every aspect. He has a hair-trigger temper and a tendency to whine and complain about everything. His biggest rival was his stepbrother Lorenzo, whom he became forced to live with after the marriage of their parents one year ago. So their parents decide to sign the two up for the race as a last-ditch effort to bring cooperation between the two and to get them to stop hating one another. Chet's normally quite lazy, but if there's an opportunity to show up Lorenzo, he suddenly becomes very motivated. Chet shows that he is skillful when it comes to gymnastics. As the race goes on, he and Lorenzo realize they have a lot in common and finally settle their differences, become good friends and accept each other as stepbrothers and family.
