A pair of beautiful young girls (Matsushita Nao, Suzuki Ami) finds themselves in the fight of their lives when a trip to a hot springs resort lands them in the middle of a remote village, where bloodthirsty maniacs carry out a terrifying tradition. Based on the spine-tingling novel by Nobuyuki Joko, this fast and funny horror-thriller is directed by cult film auteur Kenta Fukasaku (Battle Royale II).
