The story takes place in a remote and impoverished mountain village. Zhang Baomin (played by Song Yang) is a miner. One day, he is called home by his wife, Cui Xia (played by Tan Zhuo), as their son has gone missing. With a photo of his son in hand, the mute Zhang Baomin sets off on a journey to find his son. Along the way, he encounters the henchmen of the wealthy businessman Chang Wannian (played by Jiang Wu), leading to a conflict between the two sides. Chang Wannian deceives Zhang Baomin, claiming to know the whereabouts of his son, but in reality, he is hiding a dark secret. Chang Wannian has been illegally acquiring coal mines through bribery to make huge profits. As his lawyer, Xu Wenjie knows too many secrets that cannot be revealed. The public security, procuratorate, and judiciary begin to investigate Chang Wannian's company. At this critical moment, Xu Wenjie disappears. To force Xu Wenjie to comply, Chang Wannian kidnaps his daughter.
