Entering an adult prison for the first time, the teenaged Eric (Jack O'Connell) makes it a point to establish himself as a force to be reckoned with in his threatening surroundings. The violent and unpredictable convict begins working the system to his advantage and dominating those around him, until he meets Neville (Ben Mendelsohn), the inmate who will soon have a special influence on him─because he's Eric's father. Tough British prison drama co-stars Rupert Friend, Raphael Sowole. 106 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1; featurette.
