Crime Decoding: the Hidden Truth

Donghai City in China is a coastal city with a prosperous economy but undercurrents. Behind the high-rise buildings are the fireworks of the city and the abyss of human nature. The sharp contrast between the old industrial area, the old city, and the wealthy area provides natural soil for all kinds of crimes. The Municipal Public Security Bureau has established a "Special Crime Investigation Section" that specializes in solving difficult homicides, serial cases and old cases. The team members have their own unique skills. While solving each bizarre murder case, they also uncover the truth about the serial murder case that has been hidden for ten years.
