Description

Disturbing Japanese horror, directed by Takashi Shimizu. Masuoka (Shinya Tsukamoto) is a cameraman obsessed by the footage he takes of a violent suicide in a subway. When he returns to the scene, he discovers a doorway into a strange otherworld populated by ghosts and subterranean creatures, including a beautiful mute girl who he takes home with him. But when he begins to learn her secrets, he realises that he has acquired a key to access the terrible secret knowledge that he craves.
