- A Hong Kong dining mogul leaves behind a sushi restaurant to his second wife, Kong Ying-yuet (Lisa Lui), their son, Yu Chi-hiu (Michael Tse) and the son from his third wife, Yu Chi-hing (Julian Cheung). Hiu and Ying are remarkable Japanese cuisine chefs whose main aim in life is to pursue excellence in chefhood. Although Hiu and Ying have different mothers, they get along very well.
When their father's first wife, Lang Yung-yung (Angelina Lo) creates trouble for the restaurant, Hiu declares to challenge her, claiming whoever wins will have the restaurant. Yung sends her personal nurse, Choi Sze-lung (Tavia Yeung) to get close to Hiu. Hiu is smitten with Lung but soon becomes unhappy with their lukewarm relationship.
On the other hand, their supply for fresh food has been shut out. Ying has to make a trip to Hokkaido, Japan to buy fish. He meets Keung-keung (Myolie Wu), a willful girl from a wealthy family on the plane. They also meet Mo-yung Ching (Damian Lau) who is known as "The God of Fish" by chance in the fish market. As the relationship between Ying and Keung grows, Keung finds out that Ching is actually her long lost father. Ching becomes Ying's mentor and helps him through the competition to win the first overseas Japanese restaurant franchise in Hong Kong. As Ying's career grows, Hiu becomes more jealous of his brother and starts to scheme with Lung to get his father's fortunes. As Hiu and Ying meet with setbacks in their career, family and their loved ones after their attempt to save the restaurant, the two brothers decide to have a competition once and for all.
