"After School Massacre" 2014 focuses on a group of high school students who are forced to attend a mandatory after-school detention session. What begins as a typical punishment quickly turns into a horrifying fight for survival when a deranged and vengeful killer, wearing a grotesque mask, infiltrates the school. One by one, the students and faculty are targeted and brutally murdered, as the survivors desperately try to escape the school and unmask their assailant before they all become victims of the massacre.
