In the rain-slicked streets of a city haunted by its past, a brilliant but tormented investigator finds himself pulled into a chilling mystery that threatens to unravel everything he knows. Detective Hole follows the relentless and intuitive detective portrayed by Joel Kinnaman, a man whose obsessive pursuit of truth is both his greatest asset and a deep personal flaw. His investigation into a series of seemingly disconnected crimes leads him to a shadowy conspiracy, forcing him to confront his own demons and question who he can trust. He is joined by a sharp, by-the-book prosecutor played by Pia Tjelta and a mysterious figure from the criminal underworld brought to life by Tobias Santelmann, each with their own hidden agendas. This atmospheric Nordic noir weaves a complex web of deception, moral ambiguity, and psychological tension, where every clue reveals a darker layer and the line between justice and vengeance becomes dangerously blurred.
