When Nick and his pals suddenly find themselves short a man for the NBA-sponsored three-on-three tournament they plan to enter during the summer holidays, the solution seems simple enough. Nick, Kia and Mark are the key players on the team, so the fourth, though mandatory according to the rules, doesn't really have to be good at the game. A surprise visit from Nick's mother's cousin brings Ned, who is exactly Nick's age but not exactly an athlete, into the picture and onto the team. Nick and Ned, though related, are about as different as two boys born on the same day can be. And they don't get along. Nick cares mostly about sports and basketball is his passion. Ned is crazy about bugs and lives out West in a national park, three hours' drive from the nearest basketball court. The other three teammates figure that as long as they don't actually have to use Ned in a game they will be fine. Then Mark sprains his ankle and can't play in the tournament. Suddenly Nick and Kia must find a way to make Ned an integral part of the team.
