Billy disappeared after assassinating Ah Hai, the new boss of the 390 gang. Cindy was captured by the 27 gang and taken back to a massage parlor in South Village, Kepong to sell herself to pay off her father's debt. Billy successfully assassinated the owner of the massage parlor and rescued Cindy. Billy took the blame and was protected by the 390 gang's acting boss, Fire Cannon (the younger brother of the 390 gang's founder Huoshan). Billy wanted to be the 390 boss, but Fire Cannon thought that Billy was brave but not wise and was not suitable, so he only appointed him as the leader of the Five Tigers. Fire Cannon ordered Ah Zhong to come out and take the position of the 390 boss. Billy was psychologically unbalanced because of this. On the other hand, the son of the deceased 27 gang boss Black Dragon, known as the Prince, returned from Australia to take over the position of boss. The Prince managed the 27 gang with a shrewd mind and ruthless means, and sold drugs in Kepong nightclubs, turning Kepong into a "drug city" overnight.
