star Jack O'Connell headlines this uncompromising prison drama focusing on a young, compulsively violent convict who makes enemies of both the guards and his fellow inmates while locked up in the same penitentiary as his dangerous father. Eric (O'Connell) is a volatile 19-year-old whose life is changed forever when he's sentenced to serve time in an adut prison. Beset by treachery and surrounded by corruption, Eric clings to the hope of a better life while questioning whether his unpredictable father plans to protect him, or throw him to the wolves. Meanwhile, Eric participates in an anger-management group run by a compassionate psychotherapist (Rupert Friend
) who may hold the key to unlocking the source of the young prisoner's unbridled rage.
