In the late 1920s, the Yi family, a Shanghai department store tycoon, encountered a succession crisis. Yi Xinghua decided to choose a family heir from his eldest daughter Zhong Ling, second daughter Zhong Yu, and youngest daughter Zhong Xiu because his only son Yi Zhongjie gave up business to become a doctor. Zhong Ling is a lady from a famous family, elegant and quiet. Zhong Yu was raised by her Nanyang tycoon grandfather and is smart and capable. Zhong Xiu studied in the United States and is romantic and naive. The three daughters have different mothers, temperaments, and growth environments. In order to inherit Xinghua Department Store, the three have repeatedly come up with surprising strategies and show their strengths. Yi Xinghua did not expect that the return of the three phoenixes would cause an uproar. Fearing that the relationship between the flesh and blood would be hurt, he was unable to select the final heir. During the "isolated island" period in Shanghai, Yi Xinghua seized the opportunity and Xinghua Department Store prospered unprecedentedly. Most of the business income was used to help Shanghai disaster victims. But the good times did not last long. In 1941, the Japanese invaders occupied Shanghai. Yi Xinghua was killed for supporting anti-Japanese patriotic activities and firmly resisting the Japanese invaders' solicitation. Xinghua Department Store lost its helmsman and suffered a series of heavy losses, falling into a precarious situation. In order to realize their father's long-cherished wish of rejuvenating the country through industry, the children of the Yi family finally united and overcame the difficulties together.
