2045, Xinjing City. Ivy House - an old apartment wrapped in vines, hiding a set of taboo rules written in blood and ink. Former criminal policeman Lin Shen moved into Room 404 because he inherited an inheritance, but on his first day of moving in, he found a bloody number "13" on the mirror, and the countdown quietly began.
The sandalwood that is lit every day will attract withered hands in the black smoke. The elevator mirror reflects his torn mouth. There are photos of the deceased hidden under the pothos given by the old man in gray. The cheongsam in the closet carries the desperate memories of previous tenants.
Rules are the cage and time is the trap. Lin Shen must crack the secret of Qingtengju within thirty days, otherwise he will become the next soul swallowed by the rules. However, when the full moon night comes, the torn sixth rule will reveal a more terrifying truth: Ivy House is not the starting point of the rules, but the end.
This is a life and death game against time, and it is also the ultimate torture of human nature. When the countdown reaches zero, who will become the victim of the rules, and who can reveal the ultimate secret of this charade?
