Zhou Kai is a technical backbone of the Hongxing Factory, leading twelve workers including Old Wang to consistently exceed production quotas. However, because his apprentice's wife goes into premature labor, Factory Director Liu Jun forcibly docks their pay and blocks them from leaving work. Using the illegal fines as proof, Zhou Kai leads the team to resign legally and defects to a precision factory that respects technology and workers. Relying on exquisite skills, he revitalizes equipment, wins huge orders, leads his brothers to raise wages, divide shares, expand branch factories, and propel the company toward going public. Facing poaching by the old factory, rumors, sabotage, and capital's layoffs of veteran workers, he insists on using regulations to safeguard dignity, creates win-win integration through automation and experience, and ultimately allows industrial workers to ring the gates of capital.
