Inspector Nick Cafmeyer seems to have it all : the looks, the brains, the career outlook. Yet a dark shadow is hanging over his life and relationships. Since age 9, Nick has been haunted by the unsolved disappearance of his younger brother Bjorn. Based on Nick's testimony, their neighbour, Plettinckx, a known sex offender, was questioned but soon released. After all these years, Plettinckx still lives closeby and takes fiendish pleasure in harassing Nick. The only woman able to sustain an on-off relationship with Nick, is his chief, Danni, who is slightly older. She is reluctant to involve Nick in a very disturbing case: a couple have been held captive for three days by an intruder. The intruder has vanished without a trace, along with their 9-year old son Robin. Nick heads a massive search and turns it into a relentless manhunt.
