In the 1980s, Lu Mingyuan, an experienced dry goods merchant, is schemed against by his younger maternal cousin Zhang Shouye and his wife and driven out of their jointly operated shop. Drawing on years of industry knowledge and solid experience, he opens a new store right across the street, remaining committed to genuine products, full weights and honest business practices. Faced with his rivals' vicious competition, including counterfeit goods, inferior products, short weights and covert sabotage, he calmly overcomes each challenge and plans his moves carefully. He transforms his small shop into a reputable dry goods brand, while his unscrupulous opponents ultimately suffer the consequences of their own schemes.
