Law & Order: UK

When a homeless man is found beaten nearly to death in the park at the centre of a well-kept square, DS Ronnie Brooks (Bradley Walsh), DS Matt Devlin (Jamie Bamber) and DI Natalie Chandler (Harriet Walter) investigate. The victim, Roland Kirk (Sean Harris), is bi-polar, lives in a van on the square and is known to the authorities. As our cops dig deeper, they discover Kirk tormented the residents to the extent that they were desperate to get rid of him. Everyone has a motive but no one is talking. Are they all protecting the perpetrator? Is it the local courier? The angry restaurant owner? Or respectable architect, Harry Morgan (Kevin McNally) whose son has turned against him and allied himself with Kirk. When one man is charged with GBH he pleads self-defence - he was defending himself and his neighbours from the local ‘nutter’. Senior Crown Prosecutor James Steel (Ben Daniels) is determined to prove that this was a premeditated attack but Crown Prosecutor Alesha Phillips (Freema Agyeman) and George Castle (Bill Patterson) know that the jury’s sympathy will lie with the law-abiding defendant rather than the antisocial Kirk. If the ‘good-guy’ neighbour is found not guilty, the jury will have given the nod to vigilantism in all its primal brutality and undermine the very system of Law and Order itself.
