On the brink of bankruptcy, the Hongxing Steel Rolling Mill, under the leadership of its director, Lu Xiangdong, takes on a challenging foreign trade order for 10,000 valve sets. Faced with the technical monopoly and collective blackmail of Grade Eight fitters, Lu refuses to compromise. Instead, he dares to innovate, inventing a foolproof positioning fixture that breaks down complex procedures into a standardized assembly line. By shattering technical barriers and unlocking everyone's potential, he enables even apprentices and support staff to work miracles. Ultimately, the factory not only delivers the order flawlessly but also wins a lucrative long-term contract from foreign clients through outstanding quality control. It achieves an industrial transformation from rule by individuals to standardized processes, showcasing the ingenuity and determination of modern Chinese factories.
