The only borstal in Britain where girls are kept behind bars - Bullwood Hall -is tucked away in the Essex countryside. For the girls sentenced to time here, it's the end of the road. Every other form of treatment has failed. Crime amongst young girls has tripled in the past ten years so Bullwood must cope with a wide cross-section of offenders - violent and non-violent, normal and subnormal, teenage mothers, burglars and prostitutes.
Bullwood has many critics and, four years ago, the Younger Committee recommended it should close. It just wasn't suitable. All that's happened since is that the number of inmates has increased by 60 per cent.
John Pitman and a camera crew were allowed to film in Bullwood for seven days and to meet some of the girls who talked openly about their lives.
