The story takes place in a remote and impoverished mountain village. Zhang Baomin (Song Yang) is a miner. One day, he was called back home by his wife Cuixia (Tan Zhuo). It turned out that their son was missing. With a photo of his son, Zhang Baomin, who could not speak, embarked on the road to find his son. On the way, he met the minions of the big capitalist Chang Wannian (Jiang Wu). The two sides clashed. Chang Wannian lied to Zhang Baomin that he knew the whereabouts of his son. In fact, he hid a dark secret. Chang Wannian has been relying on bribery to illegally acquire coal mines to make huge profits. As his lawyer, Xu Wenjie knows too many secrets that cannot be told. The public security, procuratorial and judicial agencies began to investigate Chang Wannian's company, and Xu Wenjie disappeared at this juncture. In order to force Xu Wenjie to submit, Chang Wannian kidnapped his daughter.
