Grudge series director Takashi Shimizu sets his latest horror outing in a Mount Fuji amusement park that bears a striking resemblance to Japan's real Fuji-Q High Land and "the world's longest horror house walk-through" located there. A hospital becomes an impenetrable labyrinth when a group of teens take an ailing friend in for treatment. Before they emerge, they'll encounter ghosts, killers and more in this film starring Suzuki Matsuo and Misako Renbutsu.
