Lao Jing Wang (played by Ni Dahong) has spent most of his life in underground mines and has accumulated rich experience. He is a veritable veteran in this industry. He has brought out a group of excellent and brave apprentices and is deeply trusted and loved by his peers. Just as he was about to retire and enjoy his old age, the coal boss told him that he had to go down the mine to blast again. Who knew that it was this last task that made Lao Jing Wang encounter the biggest crisis in his career. With apprentices such as Xiao Guangxi (played by Chen Xiaodong), Lao Jing Wang and his party went deep underground. Who knew that an accident occurred during the blasting, and the mine collapsed, blocking the way back for Lao Jing Wang and others. The occurrence of the mine disaster quickly attracted the attention of the media, and the families of the trapped miners quickly gathered. Above the ground, one test of humanity after another was staged, and under the surface, Lao Jing Wang led the surviving miners to desperately find a way out.
