Twelve frightened faces were imprisoned in a strange live broadcast room called "National Trial".
Their identities are very different, but above their heads hangs a bloody countdown symbolizing death. The cold mechanical voice announces cruel rules:
Everyone must vote to execute one person every night! If no one is executed, half of the lives are randomly wiped out.
The only way to survive is to personally choose your companions to die. In this closed killing cage, suspicion and panic spread rapidly, and the bottom line of human nature was repeatedly torn apart in every vote.
A life and death game in which they themselves act as judge and executioner has begun ruthlessly with the ticking of the countdown.
