Britain's prisons have dealt with a vast range of inmates over the years – from infamous criminals to celebrities to the wrongfully convicted. Banged Up now tells the story of six of Britain's most notorious jails – Durham, Wandsworth, Pentonville, Wormwood Scrubs, Dartmoor and Holloway – and of the men and women who entered their gates, sometimes stood on their scaffolds and occasionally vanished before their time. There are famous faces like Oswald Mosley, Dr Crippen, Ruth Ellis and Frankie Fraser as well as the man who shot Martin Luther King Jr, the wartime double agent contacting Nazi spymasters with a transmitter in his cell, the doctor hanged as he smiled at the farewells of lovers, the con who defied a gangland godfather, aristocrats, arsonists and murderers. They have all been here, and the screws who guard Britain's prisons have seen it all. Banged Up uncovers the real, human, inside story of what really goes on behind the forbidding prison entrances and cell doors of Durham, Wandsworth, Pentonville, Wormwood Scrubs, Dartmoor and Holloway and reveals new stories of what life behind bars was really like for those unfortunate enough to hear the cell doors slam behind them.
