An accident caused modern detective Zhang Yunxin to travel to Ninghai County in 1990 and become the new captain of the county's criminal investigation team. At that time, there was no DNA technology and no surveillance network. Solving crimes relied entirely on feet, connections and experience and intuition. When he first arrived, he encountered a difficult "secret room suicide case": the female worker Li Mei died in a locked dormitory. There were no signs of struggle at the scene, and everyone was eager to conclude the coffin. However, Zhang Yunxin relied on the criminal investigation advantages brought by time travel and the bound [Detective Panoramic System] to see the flaws in the details. Faced with the doubts of the old-school police officers, the threats of the evil forces, and the secret operations of insiders, he joined hands with the loyal police officer Wang Lei and wandered in the gray area between the fishing port and the county town, tracing the relationship between the veteran Zhao Hu and the Haisha Gang, and uncovering the smuggling conspiracy and power corruption hidden under the surface of "murder for love." This is a journey of justice that spans time and space. It is also a passionate story about a modern detective using professionalism and courage to illuminate the fog in a retro criminal investigation environment.
