When a bi-polar man living in a camper van is found beaten nearly to death with an iron bar at the centre of a well kept square, DS Brooks, DS Devlin, and DI Chandler investigate. As the cops dig deeper, they discover that 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. James Steel is determined to prove that this was a premeditated attack but Alesha Phillips and George Castle know that the jury's sympathy will lie with the law abiding perpetrator as opposed to the antisocial victim who refuses to take his medication.
