Roy McCormick (MARTIN LAWRENCE) was once a great college basketball coach. An inflated ego, too many endorsements and a volatile temper, however, have resulted in a looking streak that has officials at Ohio Polytech University concerned. That comes to a head during yet another outburst at a game that results in him being suspended for life from the NCBA. However, Roy's quick thinking agent, Tim Fink (BRECKIN MEYER), knows that the rules state a disciplined college coach gets one more chance before such a lifetime ban.
The only problem is that no other team in any league wants him. That is, except for the kids who make up the Mt. Vernon Junior High Smelters basketball team where Roy went to school many years earlier. Realizing it's their only chance at redemption, Roy and Tim agree to the coaching offer that comes as a complete surprise to Principal Walsh (MEGAN MULLALLY). Considering that the Smelters have yet to win a game, let alone score a point, especially against the likes of the local powerhouse coached by Larry Burgess, Sr. (PATRICK WARBURTON), the principal agrees.
With the aid of assistant coach Mr. Newirth (HORATIO SANZ), Roy thinks he'll have no problem racking up the victories. Unfortunately, he's yet to meet the likes of the thirteen-year-old boys on his new team. They include Keith Ellis (OREN WILLIAMS), the only talented kid of the bunch who has no concept of team play; One Love (EDDY MARTIN), a kid obsessed with his basketball shoes and any potential endorsement deals; the diminutive Ralph (STEVEN ANTHONY LAWRENCE) who has a nervous stomach; the nearsighted Goggles (GUS HOFFMAN); and the less than intimidating Fuzzy (LOGAN McELROY).
Roy's initial approach is one of indifferent laziness that doesn't impress Keith's mom and school worker Jeanie (WENDY RAQUEL ROBINSON) who doesn't like the college coach or his attitude. When Roy's last endorsement deal is canceled, however, he suddenly finds the motivation to prove he can coach any team to victory. Adding tough girl Big Mac (TARA CORREA) and the towering but awkward band member Wes (STEVEN CHRISTOPHER PARKER) to the squad, Roy sets out to whip the team into shape and get them on the winning track.
