Plot
In the year 1990, at an out-of-the-way community center in the town of Guisari, a janitor goes on a rampage, murdering all the guest lodgers before killing himself. Ever since then, on the anniversary of the grisly event, disturbing events, including other deaths and suicides, keep taking place at the same location. As a result, the center is shut down and left abandoned for years, during which rumors abound of a ‘guimoon’, a door for ghosts in the building that should anyone enter through, they will never be able to leave the building. In the present day, renowned paranormal investigator Dojin (Kim Kangwoo), the director of a psychic research institute and the son of a shaman who died during an exorcism ritual at the center, makes his way to Guisari in search of answers. Also making the trip to the haunted location are a trio of students planning to film a video about the famed locale.
