Su Manqing, a daughter of the Guangzhou Chamber of Commerce, faced suppression from the Japanese army and traitors after taking over the family business. She meets patriotic businessman Lu Mingyuan, who helps Manqing fight against foreign enemies and protect national industry. The two fought side by side in the business war to smash the Japanese conspiracy to annex the chamber of commerce. In the process, Manqing grew from a profit-focused businessman to a patriot who cared about his family and country, and finally got married to Mingyuan.
