On the first day of tenth grader, Lee Ping is framed for a mind-blowing prank and thus is sentenced to one full year of detention and one full year of grounding. Lee's fellow inmate Biff convinces him to sneak out of detention to collect evidence from the auditorium which can prove his innocence. The only thing Lee can salvage is a camera phone which contains a picture of someone messing with Lee's bag during the Prank, and when Lee finds a match for the hand in the photo he will clear his name.
