The Nelsons finally arrive in North Wales, thinking they have escaped their tormentors. Trouble is pursuing them, however, and mein Host at the holiday camp isn't without his problematic side, either.
Firebrand Labour leader Michael Murray is swept into office on a tide of rhetoric. His first act is to "reform education", but it looks suspiciously like a personal vendetta against Mr. Weller, the headmaster who had once sent him, as a boy, to a special school for disturbed children. When Murray is summoned by the renowned political theorist, Mervyn Sloan, he is told that great things are expected of him. But Sloan also firmly insists that a general strike be called in Murray's city to challenge the Conservative Government. When one of Murray's council members, who has a weakness for the bottle, fails to ensure pickets are sent to one particular school, a disastrous conflict ensues between Murray and Jim Nelson, who is unfortunately headmaster of a school for special needs children.
Michael Murray is beginning to realise that his new-found political "friends" are not being entirely above-board with him. Jim Nelson, meanwhile, gains some respite from Murray's persecution when he becomes a local hero in a tragic accident. Though his attempt to save his pupil, Robbie Burns, is not successful, his efforts earn him the undying loyalty of Robbie's father, Norman, and his formidable brothers. After a time, however, Murray resumes the pressure and Jim begins to come unravelled, manifesting as a new phobia for bridges. His doctor refers him to a psychiatrist, Dr. Goldup. At the hotel where Murray is carrying out most of his plotting, his eye is caught by a new arrival, a beautiful and poised woman called Barbara Douglas.
