This is the story of Broadmoor's secrets and scandals. Hidden behind its walls and high up on a hill in the village of Crowthorne, Broadmoor Hospital is one of Britain's most famous and most secretive institutions. Staff at Broadmoor have always been forbidden from revealing what goes on inside. They discuss how they were harassed by and forced to fend off journalists eager for a scoop. In 2007, one member of staff was paid by a tabloid for confidential information about Peter Sutcliffe. Nicknamed 'Tipster Bob', he was eventually caught and sent to jail. In 1977, 19-year-old Colm Byrne joined Broadmoor as a trainee psychiatric nurse, and nearly 50 years on he reveals the experiences he witnessed inside the hospital that shocked him so much that he had to leave.
