A Hong Kong dining mogul leaves behind a sushi restaurant to his second wife, KONG YING-YUET (Lisa Lui), their son, YUE CHI-HIU (Michael Tse) and the son from his third wife, YUE CHI-YING (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. He is completely smitten by love for her 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 MOYUNG CHING (Damian Lau) who is known as "The God of Fish" by chance in the fish market.
As the relationship between YING and KEUNG KEUNG grows, KEUNG KEUNG finds out that MOYUNG CHING is her long lost father. MOYUNG 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 CHOI SZE-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. In this competition, HIU removes his jealousy of YING and hold a placid mood to take part in this fair competition. When the judge is going to announce the final result of the competition, YING receives a call that says KEUNG KEUNG suffered an accident and now she is in hospital. YING immediately leaves the competition whitout knowing the result. Fortunatelly, KEUNG LEUNG recovers after several days. One day, HIU tells YING that YING is the winner in last competition and he is proud of YING.
