This animated Japanese film, written and directed by Ujicha, follows an American boy, Bobby (Aoi Yûki), and his friend Akkun as they head off into the mountains after their end-of-term school ceremony. Stumbling upon a seemingly fun but highly dangerous amusement park, the two boys are attacked and trapped, alongside many other children who are also stuck there. The truth is revealed that the park is actually a trap created by a man named Koike, in order to lure in children to feed his son Takashi in this ero-guro-nansensu horror film.
