"Under the neon lights and haze of the modern city, Lin Haoran formed a special team of private detectives. The team members each had their own grievances, and due to different opportunities, they gathered at Lin Haoran's coffee shop in an old street in the city, with the mission of solving cases that were abandoned by the government and were socially sensitive but whose authenticity was difficult to distinguish. They were involved in many complex incidents such as serial murders, group fraud, old cases being overturned, and Internet-wide sensational disappearances. Behind each case were shocking social truths and deep human abyss. As each mystery was solved, the past secrets and psychological trauma of the team members gradually surfaced, and the trust within the team was constantly tested. In the end, they faced the truth that had troubled them for many years, gained growth in the process of distinguishing between good and evil, and had to experience scars and betrayals, and gained a deeper understanding of the light and darkness in the city.
