Inspector Nick Cafmeyer seems to have it all - looks, brains and a successful career. But a dark cloud hangs over his life: since the age of nine, he has been haunted by the unsolved disappearance of his younger brother. Based on Nick’s testimony, their neighbor, Plettinckx, a known sex offender, was questioned but quickly released. Plettinckx still lives close by and takes fiendish pleasure in harassing Nick. The only person who is aware of this drama is his department chief. She is reluctant to involve Nick in a new, very disturbing case in which an intruder held a couple captive for three days and then vanished along with their 9-year-old son. Nevertheless, Nick insists on heading the massive search, which turns into a relentless manhunt.
