Oslo cop Nikolai Andreassen (Tobias Santelmann) believes in doing things by the book. The charismatic man comes from a family of cops and battles constantly for justice and human dignity. But he keeps his personal life strictly secret at work. Nikolai goes on vacation back home near the Swedish border to visit his father and brother, and recuperate from a taxing investigation. When a body is found and his brother Lars, still drunk after a night of carousing, is called to the scene, Nikolai is happy to offer his professional support. Before he knows it, Nikolai becomes directly involved in an investigation that will end up turning his world upside down. His family appears to know more about the case than he would like. As Nikolai begins wrestling with his moral principles, and covering up evidence, his colleague Anniken (Ellen Dorrit Petersen) starts a parallel investigation.
