Deep in the shadows of a city, a death in which no one is innocent.
Real estate tycoon Chen Guodong is found dead in a locked room, and the five people closest to him each tell a different story. As Detective Lin Zhe investigates, he discovers that the secretary's ambition, the adopted son's dark past, the lawyer's scheming, the doctor's prescription, and the driver's silence have together woven a deadly web. The most down-to-earth of them, the driver, readily confesses, claiming he did it to avenge his sister. But a diary from thirty years ago reveals that the foundation of this hatred was a tragic misunderstanding.
This is not one person's revenge, but a work of "collective creation" carried out with unspoken understanding. Everyone contributed a piece of the puzzle, and everyone was convinced the law could not punish them. When Lin Zhe finally lays the cruel truth before them all, behind his icy gaze lies a private reckoning that began years ago.
Beneath the truth, no one is innocent.
In a web of complicity, everyone is a villain.
If the person who seems most harmless has a master key hidden in their pocket, what does that mean?
Fascinating, you can take a look
