Grassroots entrepreneur Zhou Dagang deeply cultivates the construction industry, leading fellow workers to unite and develop, establishing a labor company to implement formal guarantees for all employees and guard the rights and interests of laborers. During project construction, he adheres to the bottom line of engineering quality, resists industry chaos of bribery and jerry-building, and exposes the irregular conspiracies of bad merchants. Because he refuses to go with the flow, he suffers malicious suppression, and the company falls into financial difficulties. In times of crisis, regardless of past grudges, he leads a team to step forward and risks rescuing those trapped in a landslide. Upholding quality with his original intention and practicing the right path with goodwill, he interprets the responsibility and dignity of ordinary builders.
