When Su Li received a mysterious express delivery, after opening it, it turned out to be an old mobile phone. There is only one line of blood words on the screen: "Welcome to join the supernatural deduction and stress game, die or pass the level, please choose."
Forced into a strange world, she discovers that each copy is a carefully designed life-threatening puzzle. Midnight singing in an abandoned hospital, legends about the curse of a century-old school, the secrets of ghost village rituals... Faced with endless horrific events, Su Li can only use her extraordinary reasoning skills to find hope in a desperate situation.

When his companions fell one by one, and when the ghosts became stronger and stronger, Su Li finally understood that the purpose of this game was not to let anyone leave alive...
