Henderson Hospital in Surrey is a very unusual mental hospital. The patients live in a jungle where they must make their own rules for survival and face up to what happens when they behave like children - whether it be failing to wash up or smashing the place to pieces. Somehow they've all failed to absorb deep lessons that most of us learn as children - the lessons of give and take which enable us to love, keep jobs and friends: to belong to society. The result is officially known as ' personality disorder,' and it turns talented, energetic and often charming adults into spoiled, sometimes aggressive and foul-mouthed kids. Some are so aggressive that they've spent much of their lives in prison; some are so desperate that they've overdosed repeatedly and drifted in and out of psychiatric hospitals; most see Henderson Hospital as their last chance. Jack Pizzey and a Man Alive team have been filming the Henderson answer - a crash course in living.
