Seven years ago, a thirteen-year-old girl named Amber Bryce went missing, and suspicion fell on her boyfriend, then-17-year-old Curtis Horne. When Daisy Thorpe, who had become obsessed with getting justice for Amber's death, also ends up missing in the present day, the team is called in to investigate. 

John Michaels is a 71-year-old insurance investigator who went missing after last being seen getting into a car with two strange men. While investigating his disappearance, the team finds that he had recently tried to make amends with his ex-wife and has been trying desperately to get his older daughter on the straight and narrow. Things get strange in the case though, and all is not as it seems.
