Still haunted by his experiences on the frontlines in Afghanistan, ex-British Army soldier Sam Norwood (James D'Arcy) tries to put his military background to good use by becoming a guard in one of England's toughest prisons. What Norwood finds, however, is a world of drug use, corrupt officials, and daily violence as treacherous as the battlefield ever was. Gripping drama, based on Ronnie Thompson's semi-autobiographical book, also stars Noel Clarke, Kate Magowan. 110 min. Widescreen; Soundtrack: English Dolby Digital 5.1.
