The story revolves around the ordinary citizen Su Zhi, the psychologist Su Zhi who can see through all lies, the physicist Luo Ming, as well as the top hacker Wang Xiaokui and the forensic doctor Chen Jing. Under the "accommodation" of senior police officer Lei Tao, they formed an investigation team to handle the strangest and most difficult unsolved cases in the city.
From the live secret room where Internet celebrities died mysteriously to the perfect case of dismemberment according to garbage classification, they used their own incredible methods to solve strange cases repeatedly. However, behind every case, there seems to be a looming shadow of a mysterious organization called "Dumpling Skin". This organization seems to be playing a big game of chess, constantly using cases to test the weaknesses of human nature. As the investigation deepens, they find that the tentacles of "Dumpling Skin" have penetrated into digital networks, old cases, and even started to directly target their team. Partners are attacked, identities exposed, and tests of life and death ensue. In the end, they must face the "dumpling skin", uncover the truth of an injustice spanning two decades, and prevent an ultimate plan aimed at subverting social order.
This is a collision between reason and madness, and it is also a legend of using the most unorthodox attitude to handle the most hard-core cases. When the dust settles, this "freak alliance" has become the last and most unique line of defense to protect the city.
