1975: A young woman’s body is found beside a busy road. She’s been disembowelled - while she was still alive. Placed on her chest is a cassette player. Inside is a sixty-minute tape, playing just one song on repeat: ‘Mack the Knife’.

Detective Bill Roach will spend the next fifty years trying to catch the vicious serial killer who becomes known as Jack the Knife.

Now: Crown Woods Retirement Home. Bill Roach sits at the bedside of elderly Gillian Lake, comforting her as she slips away. But the post-mortem shows Gillian didn’t die of old age. She was murdered.

Now Bill realises there’s a killer in the retirement home. He never caught Jack the Knife… but he’ll catch this killer.
