Twelve-year-old Griff Carver knows a thing or two about fighting crime. Because Griff's not just any kid - he's a kid with a badge. And if you are a criminal, he's your worst nightmare.

Griff might be the new kid on the Rampart Jr. High Patrol squad, but he's no rookie. And he'll do whatever it takes to clean up the mean hallways of his middle school - even if it lands him in hot water.

But when Griff links cool kid Marcus "The Smile" Volger to a counterfeit hall pass ring, can he and his friends close the case? Or will Griff let down the force - and lose his badge - for good?
