Criminal police captain Ling Xiao and forensic doctor Bai Yu have been partners for many years. One is at the forefront of the crime scene, tearing away the fog with keen intuition; the other is peeling off cocoons in front of the autopsy table, using cold evidence to restore the truth. They walked side by side through countless late-night crime scenes, witnessed the most ferocious evil in human nature, and heard the silent cries of victims. With the police badge on their bodies, they must hide their regret for life and anger against crime, and use reason and tenacity to carry the weight of justice. But when old cases intersect with real murders, secrets of close relatives and sacrifices of comrades-in-arms follow one after another, Ling Xiao's tears hidden under the police badge and Bai Yu's sigh under the scalpel eventually become the heaviest and hottest medals on their road to guarding the light - it turns out that behind justice, there is always hidden struggle and tenderness.
Purpose: In the quagmire of crime, using the responsibilities of criminal police and anti-narcotics, to light the light of faith in justice.
