On a rainy night, in the ruins in the north of N city, a man's corpse was brutally treated, revealing the tip of the iceberg of a series of mysterious cases.
The new criminal investigation captain Zhou Xinyang has a distinguished background and is decisive, but he faces a thoughtful and ghostly opponent. What the murderer left at the scene was not only violence, but also an extremely cold "ritual sense", as if he was completing a job that could not be disturbed.
Jie Wei, a genius walking on the boundary between life and death. He is calm, aloof, and can understand the last whispers of the dead, but he is closed to the world of the living. His past is a deeply buried taboo stained with blood and tears.
When Zhou Xinyang's cheerfulness and high emotional intelligence collided with Xiewei's coldness and loneliness;
When the clues at the scene are corroborated with the precise data from the forensic laboratory;
As the case progresses, it gradually touches on the unresolved past that is unwilling to look back, and the secret behind the mask...
Zhou Xinyang discovered that the murder in front of him was not just for revenge or profit. An underground casino called "The Strange Cage", a bounty platform on the dark web, a sudden vivisection case... All the clues point to a deeper darkness.
Zhou Xinyang must win Jiewei's trust, not only as a colleague, but also as a partner who can be trusted to support him. And under layers of fog, does Jiewei's notebook recording the death code also hide the answer to his own destiny?
When the logic of crime and the puzzle of human nature are intertwined, what they want to solve is not only the "tail" of the case, but also the "knot" of people's hearts.
Purpose: On the journey of pursuing justice, redemption and light come from the courage to face darkness and the warmth of protecting each other.
