Detective Shen Yan was ordered to investigate the death notice in the Bell Tower Apartment, but found that the death of the deceased was strange, the doors and windows were intact, and the scene was like a perfect secret room. The painter, the down-and-out caregiver, and the timid girl living in the building all have hidden secrets, and everyone has a motive for murder.
The stopped clock tower, the curse at three o'clock, the dead in the secret room.
A murder case that seemed like revenge led to a well-planned fire ten years ago.
Survivors, Avengers, liars, masterminds... All are trapped in this apartment.
Every time the bell rings, someone is dying.
The real terror is never the ghosts, but the human heart hidden around us.
Intention: The truth may be concealed and justice may be late, but it will never disappear.
