In Binhai City, a corpse that was carefully "displayed" opened the curtain on an old case. Police elite Lin Heng, a detective tortured by past trauma, formed a temporary detective team with his new partner Qin Yue, an activist with a tough style and unconventional tactics.
They were incompatible with each other at first, but during their investigation, they discovered that all the serial murders in front of them were inextricably linked to an unsolved "Judge's Wife Murder Case" five years ago. Lin Heng's late mentor was the presiding judge of the case that year.
As the investigation deepens, a huge dark network gradually emerges. The real murderer always seems to be one step ahead. Is there a "ghost" inside the police station? When Lin Heng finds that he and his partner are involved in an elaborate revenge puzzle, they must make the ultimate choice between trust and betrayal, legal justice and personal redemption.
