"This school is dangerous."
It is an uninhabitable land. It is a land where the dead cannot exit, where they gather.
In there, an independent high school is built. A place where the living and the dead intermingle, and it is where Eun-Bi, who is given the fate of a psychic, is admitted into.
Eun-Bi listens to the stories of the dead and solves cases whilst wandering the path of ghosts hidden in the school with Seon-Woo, whom she met by chance before entering the school.
"Ah, I forgot to tell you. This is a two-story building. If you ever see a staircase leading to the third floor, don't ever go up."
