Underachieving 16-year-old Ozzie Paxton (Vincent Kartheiser) doesn't realize he's setting out on the adventure of a lifetime when he drops off his stepsister at the ritzy Shady Glen School-the school that expelled him for bad behavior. But he can't resist one last prank-a prank that will accidentally land him in the middle of an intricate plot to kidnap Shady Glen's wealthiest students and hold them for ransom. Ozzie becomes trapped inside the school, which has been taken over by a formidable security expert (Patrick Stewart) bent on revenge against a former boss. It isn't long before Ozzie realizes he's the school's only hope. Armed only with his firsthand knowledge of the school's computer systems and hidden passageways and his own talent for disrupting authority, Ozzie goes all-out to foil the nefarious scheme.
