Assistant Chief Constable of the Manchester Police, Peter Hunter, is called in to oversee the West Yorkshire Police's Ripper investigation, with the help of John Nolan and Helen Marshall, both detectives from the Manchester Police, they decide to go back and look at the crime reports from the Rippers victims to see what they could have missed.

Meanwhile, solicitor John Piggott is persuaded by the imprisoned man's mother to fight this miscarriage of justice - and soon unearths a trail of cover-ups.
