Shen Zhennan, the leader of the Hong Kong Zhongyi Hall, suddenly passed away. The cause of his death was full of doubts. Anzhi, who had been squeezed in Paramount and was redeemed by Shen Zhennan and carefully cultivated, was ordered to take charge of the gang in order to repay his kindness and stabilize the turbulent situation. The young master Shen Muyan (nickname Sisi), who had a breakup with his father many years ago and was sent abroad, returned home urgently. He wanted to find out the cause of his father's death and regain his own power, forming a subtle confrontation with Anzhi.
As the autopsy report revealed the truth about "chronic poisoning", the two gradually turned from tit-for-tat to investigating side by side. An old photo hidden in the safe implicates the old grudge between Shen Zhennan and his old friend Li Jingfeng. The collusion between Li Jingfeng's descendants and the Qinglong Gang makes the situation even more dangerous. There are traitors lurking inside, and powerful enemies outside. As An Zhi and Shen Muyan join forces to break the situation, the feelings they have suppressed for many years quietly grow - she is his nominal stepmother, and he is ten years younger than her. This love that transcends generations and goes against the world becomes more and more firm in the face of swords and life-and-death tests.
They joined hands to fight against the Qinglong Gang's siege and track down the truth about Li Hongyuan's poisoning. With loyalty as their backbone and deep love as their shield, they fought their way through the undercurrent of Hong Kong City.
