On October 13th, 1909, a man massacred the residents and managers of the orphanage in which he was employed. The place was exorcised after the tragedy several times, but everyone knows that it is still there, that it is not gone and that it won't go away. After its reconversion in a sanatorium and following too many accidents, the Christian Church stopped all activity in the place and placed it under its supervision.
Recently a group of urbexer infiltrated in and caused a containment breach. The Church sends an exorcist to ensure that what is hidden between these walls is still asleep. But the exorcist makes the mistake of taking with him a teenager too curious ... or unconscious.
