This documentary explores how Jimmy Savile - now recognised as one of Britain's most prolific sex offenders - engineered his career and lifestyle to abuse and escape detection. Savile's decades-long career of abuse seriously affected the reputation of those who failed to stop him - most notably the BBC, hospital trusts and the police - once the truth emerged widely after his death ten years ago. Seen through the eyes of those who worked alongside him and investigated him after his death ten years ago, this programme features new testimony from those who were victims and who bore witness to his crimes, while providing a vivid insight into how he courted the Establishment as a way of protecting himself.
