In the shadow of the bustling city, there is an intricate criminal network hidden. Private detective Li Ming, an ordinary but persistent messenger of justice, was involved in a life-and-death battle because of a mysterious anonymous letter. The letter predicted that wealthy businessman Lin Hao would die in a secret room in the basement at midnight. This seemingly absurd prophecy pushed Li Ming into the abyss of danger.
As the investigation deepened, Li Ming discovered that behind Lin Hao there was actually a criminal organization called the "Shadow Group" involved. Its tentacles extended to every corner of the city, and there were even insiders in the police station who tipped him off. In repeated confrontations with darkness, Li Ming experienced betrayal, threats, and even life and death tests. He fought side by side with his old partner Lao Zhang, and worked with reporter Xiao Chen to expose the truth, but when he got closer to the truth, he discovered that Zhao Ming, whom he once trusted, was actually involved.
In the tug-of-war between justice and evil, can Li Ming clear away the layers of fog and find out the real mastermind? When the truth emerges, how will he face his former comrades and current enemies?
