Screwed (2011)

Get an insider's perspective on life in some of the UK's toughest and most notorious prisons in Screwed (2011). Based on an autobiographical novel by a former prison guard, Screwed stars James D'Arcy as Sam, an ex-soldier who returns home from the war in Iraq and takes a job as a prison guard. Sam thinks that his combat days are over, but he's about to get a lesson in the harsher realities of prison life. Prison may be an all-make domain, but Kate Magowan brings some much-needed feminine flesh 58 minutes in when she bares boobs during a conjugal visit. That'll get you pulling your balls and chain!
