Masuoka (Shinya Tsukamoto), a fragile cameraman who's afraid of the unknown that he's certain lurks around every corner, is the last person one would expect to rise to the occasion when courage is needed. But that he does when he winds up with an assignment that has him looking into an urban myth about specters that supposedly haunt Tokyo's subterranean travel system in this fantastical film directed by Takashi Shimizu.
