Local boy Barry Dyson is accused of a series of arson attacks and his clandestine relationship with a former employer's daughter complicates his plea of innocence. Peggy's latest money-making scheme with old friend Denzil creates an eyesore, forcing Jack to use his artistic flair to rectify matters, before he and Blaketon resort to more drastic, and illegal, measures.
