Plot
The interlocking supernatural phenomena, horror experiences, and the temptation brought by invisible things... Although these supernatural events happen to unrelated people, they are actually closely related. Just like jigsaw puzzles, there are endless fear attacks every time they are spelled together. This is a chilling supernatural documentary series created in a brand-new way. As long as you open the treasure box that can never be opened... then you can't escape again! Opening is the period of death, and the fear of making people unable to fall asleep one after another will continue until death...
