The story takes place in winter in Norway, where the silent, introverted and hard-working Niels drives a powerful snow truck to clear the road and keep the mountain entrance to the ice town where he lives. His work was recognized by everyone, and just as he was named citizen of the year, he received the bad news that his son had died of a heroin overdose. Nils refused to accept the official explanation for his son's death, and he began a secret search for his son's suspected killer. An unexpected turn of events made him a frightening underground hero, and his identity was unknown. Via. Zhang Yongxuan Wayne
