Thirteen-year-old Cody is aching to get back onto the pitch. Last year he had a tumor removed from his leg. Though it's a struggle, Cody tries out for the Lions and makes the team as a "super sub" -- one of eleven players who jokingly named themselves that because they're never allowed to play. Secretly Cody is relieved, since he hasn't told anyone on the team that he had cancer. But then there's a shakeup in team management and suddenly Cody and the super subs are the only players left.
