Lin Mo showed the videotape to his colleague Xu Feng. The two found the date "July 15, 1983" and the words "Qinghe Town Welfare Institute" on the tape, and decided to go investigate the truth. In the abandoned orphanage, they met Lao Zhou, the caretaker who was an orphan, and learned that the video tape was related to a fire that killed 12 children 30 years ago, and that the cause of the fire was related to an orphan named "Xiaoyun".
