Twelve strangers wake up in a windowless temple and are forced to play a real-life game of werewolf. The winner redeems their memories, and the loser accepts execution - then time is reset, and everyone returns to the round table with cleansed memories to start the next round.
Private detective Lin Yu is the only loophole in this endless reincarnation. He remembered every death, every identity, every face in despair. Starting from the thirteenth round, he discovered that he could "see" the death marks remaining on others, as well as... The abnormal system light marks on some players.
Christmas Eve comes and the game continues. Lin Yu gradually realized that every identity card they drew cruelly corresponded to a sealed real-life crime. The witch had refused to save him, the hunter had violently enforced the law, and the guard's hands were stained with the blood of innocents... And his own implanted memory was definitely not the truth.
In this "Temple of Atonement" built by the obsession of the victims, finding the werewolf is no longer the key. The real way to survive is for all sinners to reach an almost impossible consensus.
This is a game of life and death within the rules, and it is also a trial of human nature outside the rules. Keep winning until you are willing to lose to yourself.
