A convicted young arsonist's rehabilitation is threatened when he is accused of a series of arson attacks - and his clandestine relationship with a former employer's daughter complicates his plea of innocence. Rob is reminded of his own troublesome childhood and tries to prove the youngster isn't guilty, but it becomes increasingly difficult when all evidence points to the contrary. Meanwhile, Blaketon and Jack team up and find themselves in a police cell when they oppose Peggy's new advertisement venture.

Rob and the team are called in when a local judge becomes the target of a series of attacks and is subsequently terrorised by a blackmailer. As they discover what sordid antics the judge gets up to behind closed doors, the case takes a sinister twist when the prime suspect is shot dead on his doorstep. Meanwhile, Peggy and David buy a radio that tunes into police channels and sell the stories to the Ashfordly Gazette, which also gives them the opportunity to teach a pompous old enemy a lesson. It's not long before an outraged Miller discovers their scheme and delights at the chance to finally throw the book at his scheming nemesis.
