Forty-year-old Edwin is a control freak, a wimp, and, moreover, the ultimate scapegoat at the high school where he works. His life is in a downward spiral: his wife has left him and his daughter wants nothing more to do with him.
When he is also bullied by both colleagues and students—and his boss denies him a promotion because of his weak personality—he has had enough. He enlists the help of a brutal, boorish gym teacher to regain his masculinity. From that moment on, Edwin decides to strike back hard. What follows is a bizarre situation in which the students are no longer in charge of the teachers, but completely reverse the roles, and the adults become the bosses of the children.
