Suddenly they woke up. They didn't know who did it. Six of them woke up on the spot. Six people with no relationship started the "survival game". A beautiful company employee, a liar in a silver swordfish suit, a dignified primary school teacher, a clean middle-aged woman, a former criminal policeman with the image of being a member of a criminal organization, there are extremely cold men hidden in their innocent expressions, where six people risk their lives to reason. The image of the horror movie memento mori.
