Description：In 1998, Hong Kong changed dramatically after its return to China. And Causeway Bay also changed dramatically at this time. Two new figures came to the territory of Chen Haonan (played by Ekin Cheng) of Hongxing Society. One is Situ Haonan (played by Zheng Haonan) of Tung Sing Society, and the other is Li Sir (played by Danny Lee) who is the new senior inspector of Wan Chai District. Situ Haonan is ambitious and has always wanted to replace Chen Haonan's position in Causeway Bay and drive him out of Causeway Bay. A Malaysian Datuk (played by Qin Pei) wants to run a gambling ship and takes the initiative to find Chen Haonan to ask for cooperation. In fact, he secretly colluded with Situ Haonan and tricked Chen Haonan. On the other hand, Li Sir developed a little feeling of hero recognizing hero in the process of tracking down Chen Haonan. There can't be two tigers in one mountain, and the final duel between the two Haonans begins!
