Documentary takes viewers inside Europe's biggest women's prison -- HMP Holloway in North London. It is an institution largely closed to the media since a damning report by the Chief Inspector of Prisons in 1995. The report followed years of turmoil at Holloway. When the new prison opened in the mid-1970s, it had been hailed as "the jail of the future." What went wrong? The foundering of the Holloway dream is a story not just about our contradictory attitudes to women law-breakers, but about contradictions inherent in imprisonment itself.
