Genius detective Lin Wei parachuted into the city team, but due to her excessive skills, she constantly clashed with the old captain Zhou Guoping. She firmly believes in the absoluteness of technology and justice, and Team Zhou only teaches her one thing: "Handling cases means handling people's hearts."
From the cases of Internet celebrities falling from buildings to serial robberies, reality continues to polish her black and white beliefs. When the investigation accidentally touches an unsolved case handled by her father, and when the mysterious "judge" sends a provocative letter to her desktop, Lin Wei understands that real darkness often comes from the same source as light.
"Your life is not yours alone." Captain Zhou's roar after her teammate was injured made her understand the weight of the police badge for the first time. She must learn to balance between love and law, procedure and conscience.
The final showdown comes, and the "judge"'s plan is directed at her family. Lin Wei must make a choice between professional beliefs and blood ties. With the support of Team Zhou, she shed all her halo and armor and faced the abyss as a pure police officer.
When everything was settled, Zhou Guoping put an old police badge into her palm: "Now, you are a real policeman."
When a new case happened, she turned to the person behind her and said, "Follow me."
——The once dazzling light of genius has been tempered into a light that can penetrate the fog and guide the direction.
Intent: This is a story about finding coordinates in the fog of human nature, and turning a sharp blade into a lighthouse through tempering experience. It asks: Does the power of a person who upholds justice ultimately come from cold correctness, or does it come from a warm understanding and persistence of the complexity of the world?
