Simple and honest Sung Lai-wo (Sunny Chan) is a close relative to the Tong family – a noble clan of Xiguan.

However, she sacrifices her youth to take care of her family business, above which she has even spoiled her sister – Tong Nga-man (Lin Xiawei).

Nga-man, with a rebellious temperament, deliberately fools around with So Fei so as to irritate Nga-wun.

While the Tong family is leading a befuddled life, the valiant mayor of Guangzhou – Wong Kai-yiu (Law Lok-lam), is shot by accident, creating a furore among the city.

Seizing the opportunity at the mayoral inauguration ceremony on the fifth day of the first lunar month, forces of evil and people from all circles that have been dormant for a while turn out in full strength to wreak havoc.
