In 1979, 42 patients at Gonjiam Psychiatric Hospital killed themselves and the hospital director went missing. Rumors and strange stories about the now abandoned Gonjiam Mental Hospital abound. An internet broadcaster recruits a handful of people for their 'experience the horror' show at Gonjiam Psychiatric Hospital, a place selected as one of the '7 freakiest places on the planet' by CNN. They are to explore the haunted asylum and stream it live on the show. To attract more viewers, the show hosts play tricks on the guests, but things start to get out of hand when they are inside the place.
