A psychopath is terrorizing Copenhagen.
His calling card is a "chestnut man"--a handmade doll made of matchsticks and two chestnuts--which he leaves at each bloody crime scene.
Examining the dolls, forensics makes a shocking discovery--a fingerprint belonging to a young girl, a government minister´s daughter who had been kidnapped and murdered a year ago.
A tragic coincidence--or something more twisted?
To save innocent lives, a pair of detectives must put aside their differences to piece together the Chestnut Man´s gruesome clues.
Because it´s clear that the madman is on a mission that is far from over.
And no one is safe.
