To resolve the problem and prevent their customers from suing them because of their mistakes Kai-fong goes to each restaurant showing them the many useful ways a bitter melon can be cooked.

On her first stop she meets Hung Hsien (King Kong Lee), a kitchen assistant and her 'dream boy' Pete Lau (Jason Chan), who is there to conduct business with the head chef.

Pete owns a fast food restaurant chain, and by receiving over 4000 units of wrong ingredients, his company is put in jeopardy.

However, Kai-fong saves him from humiliation and failure during his food show interview when she comes up with twelve delicious different dishes made with bitter melon.

Kai-fong's new tenant, renting her family's empty apartment is Hung Hsien, a Taiwanese man who has only been in Hong Kong for one month.

Even though their small family business is successful, her shallow thinking is to hook a rich guy in order to escape her fishmonger profession.
