In the early 60s, Jimmy Savile became famous as a DJ in the dance halls of Leeds and Manchester. He ran sell-out dances for young people - but was also able to exploit this position.

Top of the Pops made Savile a household name. His growing influence within the BBC and at a range of institutions enabled him to act with apparent impunity. This episode explores the appalling impact of his crimes and the difficulty faced when people tried to raise the alarm.

Savile is asked to host Jim’ll Fix It. Now at the peak of his fame and influence, Savile's status allowed him to hide in plain sight and silence the victims of his crimes.

In the 2000s, as his career and influence began to wane, Savile made increasingly desperate attempts to conceal the truth. Yet his crimes didn't come to light during his lifetime.
