When an 11-year old girl is seen being dragged into a car kicking and screaming, the police issue an Amber alert. As the minutes and hours pass by, they know their chances of rescuing the girl diminishes. As Tony Hill reviews the evidence however, he becomes less and less convinced that this is an abduction by a stranger and believes that the girl must have known her attacker. The missing girl's mother is overwrought and her stepfather has a conviction for assault. A sudden twist however changes the entire nature of the investigation leading Tony and DI Alex Fielding to realize they had made a fundamental error at the outset.
