On the first day that new detective Lin Xiaoman joined the team, he encountered the death case of an old man living alone in a secret room.
The scene was clean, and the cause of death looked like a myocardial infarction. Everyone thought it was a normal death.
Only he could see through it at a glance - it was murder!
Hollow square symbol on the wall,
It turned out to be the fatal mark in his childhood mystery that had disappeared for fifteen years!
Old corpses sinking into the river, symbolic killings, fake deaths, black industrial chains...
The real murderer wears the skin of an angel and hides under the sun.
He uses micro-expressions to deceive lies, uses details to lock in evil, and uses justice to light up the lights!
From a small case, a national criminal network spanning twenty years was torn apart!
Don't be afraid of the dark, I'll chase the murderer.
This time, all the dead souls can rest in peace!
