The trailer for Detention which will premiere at the 2011 SXSW Film Festival. Detention is a teen horror-comedy where the local students of Grizzly Lake must survive their final year of high school. Standing in their way is a slasher movie killer who has seemingly come to life. It becomes a race against time to stop the killer and save the world - if only they can get out of detention. The Detention cuts through prom. Most of them don t have dates anyway.
