In 1990, Jiang Zhongshi, a son of Liangchuan Machine Tool Factory, an old state-owned enterprise in the north, had just been admitted to the military academy. Suddenly, he was implicated in his father's economic crimes and was disqualified from admission by the military academy. He entered the machine tool factory as a temporary worker. Yuan Xiaoxia's father was also implicated by the Jiang family's problems and died unexpectedly. Four years later, Jiang Zhongshi and Yuan Xiaoxia, who were full of resentment, reunited at the machine tool factory, but when faced with the technical innovation problems of the factory, the two put aside their grudges and cooperated sincerely. Duan Yunping's pursuit of power not only destroyed Jiang Zhongshi's love, but also betrayed Yuan Xiaoxia, step by step into the abyss of crime. Jiang Zhongshi and Yuan Xiaoxia wholeheartedly explored the path of enterprise development and gradually came together. Duan Yunqiao, Yang Chunqiu and other grassroots workers became self-reliant after being laid off, worked hard, and found the direction of their lives again. After twenty years of hard exploration, Jiang Zhongshi and Yuan Xiaoxia, relying on the technical accumulation and production experience of Liangchuan Machine Tool Factory, finally made a breakthrough in the research and development of CNC machine tools, allowing the reformed Liangchuan Machinery Manufacturing Group Company to get out of its difficulties and regain vitality. Liangchuan Machine Tool Factory has become a glorious member of China's "smart" manufacturing.
