Former criminal police captain Qin Shuo resigned due to an unjust case and joined forces with Song Zhiyuan, a doctor of criminal psychology, to solve bizarre and mysterious cases that had been shelved by the police. From the "Faceless Corpse Case" to the "Time Locked Chamber", every case has hidden traces of human manipulation. As the investigation deepens, they find that all clues point to philanthropist Su Mingche, a philosopher who uses human life as a pawn. The cowardice of forensic doctor Fang Tan, the ambition of detective Ding He, and the secret of intelligence dealer Yue Sanniang, all forces are intertwined into a network. While Qin Shuo and Song Zhiyuan were chasing the truth, they also uncovered each other's deepest scars step by step.
