Desperate to understand the madman’s intentions, Masuoka returns to the scene, inadvertently opening a door into a bizarre and horrifying underworld. Here among the ghosts and creatures he finds a strange and beautiful mute girl. After kidnapping her, Masuoka discovers evidence of a chillingly inhuman nature and realizes he has discovered a truth too frightening to be real.
