Stavern 1983: Christmas is approaching, snow is falling heavily, and a young ambitious policeman named William Wisting has just become the father of twins. After a brutal robbery he is edged off the investigation by more experienced officers, but soon he is on another case that is not only unsolved but has not even been recognised as murder. Forgotten in a dilapidated barn stands a bullet riddled old car, and it looks as if the driver did not get out alive. This case will shape William Wisting as a policeman and give him insight that he will carry with him for the rest of his professional career: generations form an unbroken chain.
