Penned by the mighty hand of Alan Bleasdale (Boys From The Blackstuff), GBH tells the story of two men; Michael Murray, an ambitious and charismatic politician; and Jim Nelson, a respected headmaster at a school for disturbed children. Both are citizens of a northern city, lifelong supporters of the Labour party and undergoing an intense period of stress. Both believe that they're being driven insane.

While Murray seeks revenge in what is initially a one-sided fight we slowly discover the secrets in his past that will cause his carefully constructed world to unravel. Then, when the pressure of public life and power games start getting on top of him, a beautiful woman arrives on the scene...
