Detentionaire (2011)

Lee Ping is an average high-school student until his first day of 10th grade, when he is framed for a major school prank and punished with a year's detention. Every day he sneaks out of detention with the help of his friends Cam, Holger, and Biffy to try to figure out who framed him and what really happened. During his escapes he must avoid being caught by Principal Barrage. Along the way he discovers that there is much more to the school, his family, and everyone around him than he thought.
