Lu Chen, a top agent who has retired for ten years, runs a car repair shop in a village in the city. His only daughter, Xiaoman, is the whole meaning of his life.
Until that day, Xiaoman was blocked in the toilet by the wealthy daughter Su Tingting - pushed, insulted, hit her head heavily on the sink, suffered intracranial hemorrhage, and her life or death was uncertain.
Outside the ICU door, Lu Chen saw the surveillance video. The perpetrator filmed Xiaoman's miserable condition and posted it online with the caption: "Not dead yet? What a pity."
The Su family sent a lawyer - a blank check, signed a confidentiality agreement, and the matter was "over". Lu Chen tore up the agreement and threw it back in the other person's face: "Let your boss come in person."
That night, Su Tiancheng woke up from his sleep and found a note on the bedside——
"Your daughter owes my daughter her life. I'm here to take it."
Seventeen cameras went black at the same time, and the secret ledger that had been hidden in the study for ten years disappeared.
The police are arresting him, the rich are offering a reward for him, and the whole Internet is watching him.
The silent man who makes a living by repairing cars is gradually uncovering the city's deepest secrets.
This time, his code name is not "Yam Luo". It's the father.
