It's every parent's worst nightmare - your child abducted and murdered. Their body found hundreds of miles away.For Andy Cardy this was a shocking reality. After his nine-year-old daughter Jennifer disappeared in Northern Ireland in 1981, the entire local community banded together in an effort to find the little girl. Days later, Jennifer's body was found floating in a dam over 10 miles from where she went missing. With no leads or clues, the trail for her murderer went cold. But nobody could have predicted this was the work of a disturbing serial killer.Over the next five years, three more young girls were snatched from plain view – vanished, in a matter of minutes. The tragic discoveries of their bodies, days - sometimes weeks - later, suggests the work of a calculated, sadistic, travelling predator.Detectives from multiple forces attempt to join the dots between these child murders using antiquated policing systems. Police technology is in its infancy - without vehicle registration recognition, CCTV, or even fully-fledged computer systems - can they close the net before the killer strikes again?A devastating impact is left on the families of these victims - Jennifer Cardy, Susan Maxwell, Caroline Hogg and Sarah Harper. Parents who'd expected to see their daughters again are now left hoping for justice.As the years tick by and hundreds of suspects are eliminated, it feels inevitable that another child will be snatched. But could a stranger-than-fiction arrest in a quiet rural village, after a local officer makes an appalling discovery, prove pivotal in the case? Will this serial killer of children ever be caught?

And with a distinct lack of physical and forensic evidence, detectives face one of the biggest challenges of their careers. Can they prove that Black is responsible for the vicious murders of girls as young as five years old?

As they prepare for a conclusion to the case - can justice ever be done? Will the tireless police work hold up in court and convince the jury? Or will Black slip through the net?Following the turn of the millennium, police from Northern Ireland re-open the 20-year cold case of the murder of Jennifer Cardy, strongly suspecting that Robert Black is the culprit. After years spent building a circumstantial case, the final piece of the puzzle could come in the form of a confession. They decide to interview Robert Black, opening themselves up to the mind of a cold and calculated serial killer.Finally, 30 years Jennifer's murder, Andy Cardy waits to come face to face with his daughter's killer in the conclusion to a heartrending story that spanned more than three decades.
