A former medical examiner is haunted by a haunted video that cannot be deleted. In the picture, the door of Ivy Apartment 404 always opens silently. He was led into the haunted house by the words "Come and see if it's true" on his old mobile phone, but became the "only audience" of this unknown supernatural live broadcast. Now, mobile phones automatically count down every night to preview the next act of the "one-act play." Children's cries came from the wall, warnings written in blood, and those selected by the video were disappearing into the darkness of the foggy city one after another. When science's unexplainable gaze fell, this forensic doctor who was accustomed to dissecting the truth found that he was gradually becoming the most satisfactory actor on the "it" stage.
