In the first of two programmes Man Alive was allowed to move freely and speak face to face with the prisoners themselves. And this programme is the viewpoint - often bitter and cynical - of the men inside. Next week, some of the same men are transferred to a new experimental prison. 1,500 men serving sentences which range from 12 months to life; for crimes which vary from motoring offences to murder. Men crammed, often three to a cell in a Victorian prison, originally built in 1851, to house only 700 Men who say they are treated like animals. Men who say that, for them, prison is only punishment. Men made bitter, angry, apathetic -men likely to come back again to serve yet more time inside. Rule number one of the prison service is to encourage convicted men to 'lead a good and useful life.' But how can anybody do this in conditions like those in Wandsworth?
