Japan does the violent porno horror thing better than anyone else and this oddity features butt-walls, weiner-eating and demon hookers. The directorial debut from the writer of Mutant Girls Squad, the film follows the ill-fated decision of a group of baseball players to give their 40-year old virgin teammate a bachelor party at the mysterious new Shogun Massage Parlor. After much bloody mayhem ensues, the survivors must team with a beautiful sex worker to try to destroy the horny house of horror for good.
