Plagued by a former grudge, Noble's opinion of the victim clouds her judgement when she begins searching for a motive for the attack, but soon realises that the most likely suspect may be in fact be the man's wife. Meanwhile, Webb and Walker investigate an arson attack on a flat set for demolition on the Aldbourne estate, but have to contend with an action rights protester, who decides to go lone ranger and steal a digger belonging to the contraction company, and a dad determined to protect his son from a life of unemployment and drugs.
