Under the fireworks in the city, there is a surging undercurrent; in the night of the city, evil lurks.
Jing Yuan, the captain of the Municipal Criminal Investigation Detachment, is calm, decisive, and thoughtful. He uses files as armor and the truth as a sharp blade. He is stationed at the forefront of pursuing criminals, countering fraud, and investigating cases and arresting criminals all year round.
He has no interest in fame or love. He only has the truth in his eyes and justice in his heart. Faced with a confusing series of murders, carefully laid out secret room plots, missing cases that have disappeared, and old cases that have been buried for many years, Jing Yuan leads the criminal investigation team to dismantle the criminal methods from the smallest traces and trace the source of the crime in layers of fog.
Tiny physical evidence solves the perfect murder case, and logical deductions reveal the conspiracy of people. They shuttled between the light and darkness of the city, dismantling every deliberately disguised killing, and exposing every greed, paranoia, and evil thought hidden deep in human nature.
Chase the murderer thousands of miles away, without fear of danger; in the name of being a police officer, you protect one side.
There is a thin line between the abyss of sin and the right path in the world.
