Lin Mo, who has both legs amputated at a high level, was complained by his neighbors for making noise late at night and performing tap dancing to disturb the residents. The police came to install a decibel meter to monitor the house. The noise suddenly exploded late at night. The police broke in and found that Lin Mo could not stand at all. Weird noises came from the ceiling, and everyone went to room 1201, which had been vacant for a long time. As clues such as black cats, wooden boxes, and missing residents emerged one by one, a well-planned malicious trap and the desperate cry for help of the trapped people finally came to light.
