In the chilling Danish thriller The Chestnut Man, a series of gruesome murders grips Copenhagen, each crime scene marked by a small, handmade figure of a chestnut—a calling card from a killer with a deeply personal agenda. Detective Naia Thulin, played by Danica Curcic, is a sharp but disillusioned investigator paired with the ambitious and intuitive Mark Hess, portrayed by Mikkel Boe Følsgaard, a transfer from Europol. Their forced partnership quickly becomes the only hope of stopping a relentless predator who seems to be targeting the families of powerful politicians. As Thulin and Hess dig deeper, they uncover a web of secrets, corruption, and a long-buried trauma that connects the victims, all while racing against time to decipher the killer's cryptic message before another life is claimed. This atmospheric and deeply unsettling Nordic noir weaves a tense, psychological puzzle that explores the dark intersections of justice, vengeance, and the sins of the past.
