In need of money to pay her basketball fees, fourteen-year old Malia King registers for a refereeing course at her middle school. Refereeing gives her a whole new perspective on the game, and helps to improve her own play. But things get complicated when Malia is assigned to referee her younger sister Flo's games, especially when she makes a call that leads to a big loss for her school. As people around Malia start pressuring her to favor the team from her own school she has to choose between calling a fair game or becoming a social outcast.
