Female detective Song Hanzhen receives an ordinary disappearance case, but unexpectedly gets involved in a series of unsolved cases. During the investigation, she teamed up with criminal policeman He Yanzhao and media person Ji Siyao to gradually uncover a number of bizarre incidents in urban gray areas. Each volume focuses on a core case, with the main plot interspersed with sub-plots involving disappearances, disguises, manslaughters and black transactions. As the truth gradually emerged, Song Hanzhen also came face to face with the secret pasts of each team member. Behind the case lies the fragility of human nature, the pull of family affection, and the fierce collision between justice and desire. Multiple threads are advanced in parallel, layer by layer, and finally all the clues are gathered in the tenth volume, ushering in the truth and self-salvation.
