Within seven days, the haunted house becomes hell. Resentful spirits seek life, and living people are like bait.
In order to survive, Chen Mo was forced to sign a blood contract and move into the famous murderous house in Qingzhou City. He possesses psychic powers and can sense the remnants of the dead, but he does not know that he has become a key piece in someone else's chess game.
There was a strange noise in the house every night, the dark shadows in the mirror were moving, and the people peeking behind the crack in the closet door were like shadows. The resentful spirit "Yaya" of the little girl who died tragically, with the overwhelming resentment of being deceived and trapped to death by her loved ones, regarded him as a new plaything and target of revenge. Should we follow the "rules" and survive, or should we explore the truth and fight back?
When good intentions turn into curses and loved ones turn into shackles, the only way to survive may be to complete the unfinished obsession of the deceased.
Chen Mo soon discovered that this was not just the evil spirit causing trouble. Behind an ordinary murder case, there are hidden horrifying rituals for evil cultivators to create "resentful evil spirits", numerous doubts within the Inspectorate, and a shocking conspiracy aimed at opening the "Gate to the Netherworld." The ancient key that can communicate with yin and yang, the broken mirror with the mother's remnants sealed inside, the torn photo... All the clues point to the full moon night three days later.
Time is running out and murderous intent is everywhere. He must uncover the truth behind the murder and prevent the evil god from coming amid the pursuit of the evil spirits, the official round-up and the calculations of the mastermind behind the scenes.
However, when the final secret was revealed, Chen Mo realized in despair that the deepest malice often stems from the truest promises. And he himself, from the moment he stepped into the haunted house, had already been part of the contract of the resentful spirit.
