Construction site maintenance worker Zhou Qifeng has handed over his entire salary to his family for nine years, risking his life to support them, yet he is humiliated by his wife Luo Huiqin even for buying pigs' trotters costing 25 yuan. After saving someone, he resolves to end this oppressive marriage. During the divorce cooling-off period, he is maliciously scapegoated by his superior Cao Guangming and framed to pay two hundred thousand yuan, while Luo Huiqin joins outsiders to suppress him. Refusing to compromise, Zhou Qifeng gets fired by the company and blacklisted by peers, but fortunately, his good friend Wu Xiangcheng sticks by him through thick and thin, and the two team up to establish their own business taking on maintenance jobs, carving out a new path relying on their craftsmanship.
