At 2:47 in the morning, Pei Zhao, the head of the Linchuan Crisis Intervention Center, received a call.
The man asked: "Is it too late to open the door that was not opened ten years ago?"
Six minutes and 48 seconds later, the call was disconnected. When the police broke down the door, the man was already dead, and a charred number plate from the White Tower Juvenile Behavioral Correction Center was left at the scene.
Lin Shen, who was entrusted by the family to sort out the belongings, accidentally cut himself after seeing "17" on the number plate. Four days later, another old man from Baita called the hotline and asked Pei Zhao to ask No. 17 Before he died.
Ten years ago, the White Tower fire killed seven teenagers; ten years later, the staff at that time received anonymous messages one after another and were asked to confess to the same hotline. Some people forced them to speak, while others took the opportunity to silence them.
Pei Zhao traced clues from phone calls and recordings, and Lin Shen identified the old site of the White Tower based on relics and incomplete memories. Pei Zhao asked him to report the crime immediately after receiving the threat and not to act alone, but Lin Shen repeatedly hid the news and insisted on investigating on his own.
As insiders die one after another, can they recover the testimony that was deleted ten years ago before the next hotline rings?
Purpose: Late testimonies should also be preserved, and perpetrators must be held accountable.
