Twelve young people with special skills received the same invitation letter from the billionaire Zhao Tianlong - if they clear the twelve secret rooms, they can share 100 million in cash equally. The temptation was irresistible, and they set foot on the isolated island and entered the gorgeous and weird manor.
At first, the game was just a game: a precision instrument room, a data maze, a historical puzzle gallery... They relied on their top professionalism to become unstoppable. Until he stepped into the secret room called "Judgement Room". The rules mutate, suspicions breed, and the first deceased appears. The death is cruelly consistent with the theme of the secret room. On the radio, Zhao Tianlong's voice was as cold as ever: "This is also part of the game."
The cooperation collapsed instantly, and the secret room turned into a hunting ground. Hackers discovered that surveillance had been tampered with, doctors detected unique toxins on corpses, and mechanical experts saw that the exquisite design of the killing mechanism pointed to the inside. Everyone is forced to face the truth: the murderer is among them, and is using each other's expertise to arrange "impossible crimes."
As deaths follow one after another, a more terrifying pattern emerges - all the dead are secretly connected to a tragedy that shocked the city a few years ago. When the survivors break into the hidden control room, they finally see the true reason why they were chosen: no one is innocent. And behind the screen, the "Zhao Tianlong" who controls everything seems to be no longer alive...
Is money the only reward, or is the price already marked? When the last secret room door opens, what awaits them is freedom, or a truth that is far more bloody and desperate than money?
