Synopsis

Over twenty years prior, a natural disaster hit the city of Wuxi. Running out of food supply for the citizens, governor Hong Chi-Wing (Wong Wai Leung) used the city's military food supply to feed the citizens. A few days after the disaster, an official of Beijing arrived to the city to check the military supply. Seeing an empty trailer, the Hong family were sentenced to death. Hong Po-Yin (Sheren Tang) escaped from punishment and became a maid in the Prince's mansion with the name Hong Po-Kei.

Twenty years later, Po-Kei meets the rich rice merchant Chiang Kiu (Elliot Ngok), whom she was betrothed to before the disaster, at Chiang Kiu's manor while the Prince was there for a visit. Chiang Kiu's wife, Yan Fung-Yee (Susan Tse) recognizes her and reports her crime to the Prince. Chiang Kiu manages to convince the Prince to free her, and marries Po-Kei as his fourth wife. Chiang Kiu appreciates Po-Kei's wisdom and persistence, and decides to entrust his business to her, telling her to find a suitable successor for him before he dies.

Hungry for power and eager to keep tradition, Fung-Yee finds every opportunity to only let her son, the eldest child Chiang Bit-Man (Pierre Ngo) to be the only heir of the family business. She tries to strip Po-Kei from power, but lost all hope when Chiang's final will reads that Po-Kei should be the full owner of the business.

Despite all the attacks in the family, Po-Kei manages to keep the business in good shape. She has never forgotten Chiang Kiu's last wish, which was to find an heir in the family. She is impressed with second son Chiang Bit-Ching (Ron Ng) and guides him to become the successor, but her efforts are met with Chai Kau's (Wayne Lai) challenges. Chai Kau seeks vengeance for being mistreated and wants a pay back from Bit-Man and the Chiang's family uncle, Pang Hang (Lei Seng Cheung). After rounds of battle wits and actual fights, Po-Kei and Chai Kau begin to appreciate and help each other.
