Interpol Lin Hao died mysteriously, and all clues were artificially wiped out. As an interpol, his brother Lin Yan refused to accept a hasty conclusion of the case.
A sudden kidnapping imprisoned all those involved in the case into a secret room full of polygraph torture equipment, and a confession game with life as a bet began.
Every lie will trigger a fatal electric shock, and every round of choices has hidden traps. This group of people with their own sins are tearing each other apart, and a black trade of illegal organ harvesting gradually comes to light.
Someone is carefully laying out the chess game in the dark, and everyone is just a bargaining chip to be sacrificed. While Lin Yan was surviving in the death game to collect evidence, he was following clues to track down the real behind-the-scenes banker behind top-level capital and high-seas cruise ships. Under the abyss, no one is a pure avenger.
