Nick Cannon plays Tracy "Tre" Stokes, a streetwise LA cop in "Underclassman," which combines frenetic action with sharp-eared comedy. When a student at an elite private school gets murdered, the rough-edged rookie Stokes gets assigned as the undercover detective to track down the killer. The resulting culture shock is only one of his difficulties. The ever-resourceful Stokes resorts to using his unique blend of sharkish good cheer and rakish charm to woo his beautiful teacher Karen Lopez (Sanchez) to help him pass Spanish and his arrogant athletic prowess to make the school streetball team. Once Stokes gets "in" with the edgy team captain and lead suspect Rob Donovan (Ashmore), he discovers that Donovan is being coerced into participating in a student car theft operation. Using his talent for hunches, Stokes wastes no time employing unorthodox methods of investigation. Although disapproving of Stokes behavior,

Captain Victor Delgado (Marin) is worried for his safety and assigns two of his detectives as back up - Detective Lisa Brooks (Hu) and Richard Gallecki (Gomez) to keep an eye on him.
