In the cold winter in the north, in a mining town in the north, a shepherd boy walked in the mountains with his sheep and stopped by a shallow river ditch to look into the distance. Two days later, the miner Zhang (Song Yang) learned that his son was missing and hurried home. Three days later, the daughter of lawyer Xu Wenjie (Yuan Wenkang) also disappeared. He picks up the phone and calls the only suspect he can think of-Zhang Wannian (Wujiang), a black-and-white coal boss.
The dumb man who lost his son and could only talk with his fists, the lawyer who cheated him out of court, the nouveau riche who loved charity but did evil behind his back, all the original sins contained in human nature were infinitely magnified in this film, and people looking for children in mines and wilderness were lost in it. Two cases of disappearance that had nothing to do with each other were accidentally linked, suddenly fell silent and crashed into the floor.
