Ten of the most dangerous and disruptive men in the prison system have been brought together in an experimental unit at Hull Jail. A new softly-softly regime is being tested on inmates like Fred Low, who is serving three life sentences - one for killing a fellow prisoner - and Patrick Mackay, serving five life sentences for manslaughter and robbery. 40 Minutes gained access to the unit as the prisoners started to reveal themselves to the hand-picked staff, and as conflicts began. The most serious clash was over the only woman working full time in the unit, and it involved David McAllister, serving 19 years for armed robbery and assault, who later escaped from the unit and was on the run for five days. This film tells the story of the most controversial unit in our prisons.

In New Jersey, USA, a team of cops and scientists is 'busting' polluters. For the first time a film crew has been given total access to their operations. 40 Minutes follows the trail - the surveillance. the 'sting', the raid. Whether it's one small operator dumping chemicals on the street or the president of a multi-million-dollar company caught polluting a river - both are likely to face serious criminal charges. In New Jersey, they believe only tough action will deter dumpers. Is there a lesson for us in Britain?

Two children who feel sure they died terrible deaths and have been born again tell their extraordinary stories. Nicola, aged 12, lives in Keighley, Yorkshire, near to the railway tracks where she played in the 19th century in another life. Then, she says, she was a boy. Parish records suggest that it isn't just a childhood fantasy. Titu, aged 6, lives in north India in the shadow of the Taj Mahal. His is a violent story. He alleges he was gunned down by a murderer. Another vivid imagination? The radio shop he ran still exists, and his widow is still alive. When he mentions buried gold, it seems to jog her memory...
