A model citizen defends himself against a mentally ill drifter and the law becomes a minefield for the officers trying to enforce it… Kirk (Sean Hughes – The Last Detective) is bi-polar and lives in a campervan on a well-cared-for residential square. He's not really welcome there and taunts the residents with his presence. So, when Kirk is found brutally beaten, detectives Ronnie Brooks and Matt Devlin discover their list of suspects is long. The locals close ranks, though, unprepared to give up the person who did what so many of them wanted to do. That’s until the police arrest the wrong man… The courage of his convictions desert him and he sets Brooks and Devlin on to architect Harry Morgan (Kevin R McNally – Pirates of the Caribbean). Morgan's son preferred Kirk to his family and Morgan didn't like that. He's charged with causing grievous bodily harm (GBH) but claims he hit Kirk in self-defence. Prosecutor James Steel has problems with that story, though, because Morgan took an iron bar with him when he went to see Kirk. If he'd taken a six-pack, the court might believe he went in peace, but an iron bar... James's assistant, Alesha, is sure the jury will have sympathy with concerned father Morgan, not trouble-making Kirk. But James does not want a vigilante getting a pat on the back in his court...
