After a woman is discovered stabbed in the eyes and incinerated in her car she is identified as Claire Somers, a neglected child who was taken into care, then later kidnapped in 1986 at the age of seven. Robert Fenchurch had his eyes stabbed out on the night Claire was kidnapped as her abductor fled the scene. The team soon find out that Claire had snatched 15-year-old Abigail Harding, who was found locked in a hotel room.

The investigation into Claire Somers' death has seemingly unleashed a predator straight from the darkest childhood nightmare. But are they looking for a monstrous child-stealer, or misguided saviours?
