Gun master VS criminal investigation hero.
Ten years ago, Wuchuan detective Song Huai was shot, leaving an unsolved case.
Ten years later, Song Lingshu returned to the criminal investigation team where his father belonged during his lifetime.
In order to explore the truth of that year, she delved into the field of firearms ballistics and weapon evidence, developed rare professional skills, and worked side by side with captain Xie Zhao to pursue the murderer and solve the case.
In the market, mysterious cases occur frequently.
A good man died tragically, the murder was hidden in the recording, a substitute died in the fire, a fake murder in a secret room, and an execution with a traceless chamber pressure. A series of perfect crimes that seemed to be accidents, suicides, and revenges were layered and full of mystery.
The murderer is well versed in blind spot tricks and uses unpopular tactics to cover up his crimes, repeatedly stymieing conventional criminal investigations. Song Lingshu breaks the illusion with micro marks, breaks blind spots with professionalism, dismantles the layers of disguise, and catches the evil in the world.
She walked through countless crime scenes, cleared away countless fogs, and slowly pieced together the truth about the gunshots ten years ago from the scraps of physical evidence and niche clues.
One day, her injustice was overturned, and she took over her father's police call, sticking to her original intention of serving as a police officer and protecting the peace of the city.
