A series of bizarre murders broke the peace of the city. The seemingly unrelated victims have countless connections hidden behind them. The protagonist Lin Yu, a former prosecutor who has been frustrated in the judicial field and has a righteous heart, is determined to explore the truth alone after the mysterious death of his best friend.
As the investigation deepened, Lin Yu discovered that a mysterious organization was involved in the case. This organization carries out lynching punishments in the name of judging crimes. Members of the organization use online platforms to expose information about so-called "sinners", incite public sentiment, and then carry out deadly revenge.
In the process of pursuing the truth, Lin Yu encountered many obstacles. The mysterious organization pressed him step by step, trying to prevent him from uncovering the truth; the police also had doubts about his investigation due to insufficient evidence. At the same time, Lin Yu also had to face his own inner struggle. His previous setbacks in the judicial system made him doubt the way justice is achieved.
Lin Yu did not give up. He relied on his keen insight and tenacious perseverance to peel off the clues. Every time he gets closer to the truth, there is greater danger, and his family and friends are also drawn into this dark whirlpool. But Lin Yu always sticks to his faith and makes difficult choices between the law and lynching, justice and revenge. Can he finally succeed in exposing the true face of the mysterious organization and allow true justice to be done?
