Reporters Alys Harte and Bronagh Munro launch a forensic and serialised investigation into a teenage boy who mysteriously vanished on the Isle of Wight 20 years ago. In 1996, 16 year-old Damien Nettles went missing after a night out in the small town of Cowes. Nearly two decades later, his body has never been found and no one charged. The big question remains - was Damien murdered? And if so, who was behind his death and disappearance?
