Lin Qiang, the owner of a repair shop, is brutally attacked and his business destroyed after refusing to give Zhao Dabiao, the local tyrant who throws his weight around town, free service. With his livelihood cut off, Lin Qiang starts from scratch by collecting scrap to support his younger sister's education and uphold his principles. From repairing old freezers and dismantling discarded cables to competing for contracts at construction sites, he gradually builds a legitimate recycling factory. Refusing to back down, he gathers evidence of the bully's illegal dealings and ultimately sends Zhao Dabiao to prison. Now he has reopened his old shop as a community service center, hoping that more ordinary people who earn their living through hard work can hold their heads high.
