In Copenhagen, a young mother is brutally murdered in a playground, her body mutilated, and a small, unsettling figurine made of chestnuts and matchsticks left beside her. This discovery marks the beginning of a terrifying series of killings, each accompanied by the signature "chestnut man." Detectives Naia Thulin and Mark Hess are assigned to the case, which takes a disturbing turn when a fingerprint on one of the dolls is identified as belonging to a government minister's daughter, who was kidnapped and presumed dead a year prior. The investigation forces the detectives to confront dark secrets and the possibility that the presumed dead girl may still be alive, while the killer's motives hint at a deeper, more twisted agenda. As the body count rises, Thulin and Hess must navigate a complex web of clues and personal histories to unmask a killer whose mission is far from over.
