In the 1930s, when the Nationalist Government ruled China, triad leader SO FEI (Raymond Wong) operated a coolie business, but due to financial difficulties, he tried befriending the simple-minded SUNG LAI WOH (Sunny Chan), whom he had misunderstood to be a relative of the wealthy Tong family. To his surprise, LAI was just small potato in the Tong family, the actual head of the Guangzhou business world was -- the eldest daughterin the family, TONG NGA YUN (Sonija Kwok). Not only does YUN have money and power, she's also a bold, daring and courageous woman, but unfortunately she sacrificed her youth for her family business. She also spoiled her younger sister TONG NGA MAN (Lin Xiawei). MAN is a rebellious young woman and deliberately started dating SO FEI to irritate her sister. When the Tong family were living in an aimless life, Guangzhou's powerful mayor WONG KAI YIU (Law Lok Lam) unexpectedly gets shot, shocking the entire city. LAI, who had a mysterious identity, was appointed as the new Guangzhou mayor...the inauguration ceremony happened on the 5th day of the Lunar calendar, which was also the day where the evil doers started causing trouble.
