In the 1990s, Wang Dahai, an adopted son, upholds filial piety and responsibility amid family upheaval, devoting himself to protecting his elders before taking over the aluminum factory. He runs the business with integrity, defends his rights through legal means, leads workers in expanding the market, promotes standardized corporate development, and creates jobs for people in neighboring communities. Faced with the temptation of personal gain, he refuses ill-gotten wealth, stands firm on his principles, and helps reconcile the family.
