In 1999, the bell rang for bankruptcy and liquidation of Dongfeng Machinery Factory in the northeastern Liaoshen industrial town. Chang Shoushan, an old technician, found in the tool box left behind by his father that the "Special Bearing Precision Machining Atlas" related to the national military project was missing. At the same time, his daughter suddenly suffered from a rare serious illness, and 800,000 overseas surgery expenses were imminent. Fa Xiao Shen Qingnian - today's private entrepreneur came to the door with millions of cash, using treatment as a bargaining chip to ask for the core technology of the map.
Chang Shoushan, who is eager to save his daughter, is in a desperate situation between "shouyi" and "saving his daughter". The old workers went their separate ways, with only Fatty Wang and Li Jianguo sticking around. Uncle Zhou, an old engineer who stayed behind closed doors, hid clues. The "rebellious" design drawn by his daughter using 3D modeling actually hid key parameters that were missing from the map. From the iron box at the bottom of the abandoned quenching furnace, to the two-person combination of the bank safe, from the secret embroidery pattern in his infancy, to the suspicion of his father's death, clues are intertwined in the dust of the times.
Behind the cooperation is an undercurrent of betrayal, the mystery of one's life is hidden under family ties, and traditional craftsmanship has encountered the dual impact of environmental protection policies and modern technology. When the national military industry department offers an olive branch, when Shen Qingnian turns out to be his half-brother, and when the conspiracy of overseas forces and capital comes to light, Chang Shoushan will eventually ignite the eternal steel fire between personal difficulties and the righteousness of the family and country, adhering to tradition and innovative inheritance, and guard the roots and soul of the old craftsmanship.
