Lin Chen, owner of a processing factory, fell deeply into debt when his business partner's venture exploded, and when he sought help from friends he had previously supported, he was mocked instead. He sold off assets to pay debts, and taking veteran workers to set up a stall and take orders in the suburbs, he slowly revived his career with solid craftsmanship. His envious friends repeatedly maliciously intercepted orders and stole process data, attempting to illegally win a municipal project. Lin Chen calmly gathered evidence, set up a trap to counterattack, and exposed all their illegal operations at the project verification site. Facing the down-and-out former friends pleading for mercy, he calmly confronted them and completely settled the betrayed camaraderie.
