After the Tuen Mun district representative of the Hongxing Society, Dinosaur, was killed by the East Star Society's Yaoyang, the leader, Jiang Tianyang (played by Wan Ziliang), decided to choose one from Shan Ji (played by Chen Xiaochun) or Sheng Fan to fill the vacancy. Hong Kong Island representative Haonan (played by Zheng Yijian) knew the pressure of this position and strongly advised Shan Ji to give up competing for power, but his persuasion was futile. Sheng Fan colluded with Yaoyang to suppress Shan Ji, leading to the tragic death of Shan Ji's friend, Da Tian Er. On the other hand, a teacher named Xin Xin (played by Li Jiaxin) from a secondary school in Tuen Mun had always disliked the triads, but her impression changed after getting to know Haonan, and she developed feelings for him in a short time, leading to a one-night stand. However, due to living in two completely different worlds and Haonan's inability to forget his ex-girlfriend (played by Li Zi), their relationship was destined to come to a fruitless end.
