Rina worked for a travel agency, managing the "Onihime-mairi" tour. She was to guide visitors through Matsusawa village, known for its spiritual legends. Horror-loving couples and groups would join a spooky day trip, which appeared to be a fresh start for Rina. However, the tour participants had planned this itinerary. In a remote mountain village, the men in their group would push the girls to new heights through their sexual desires. Little did she know that spirits were controlling all of them.
