Attracted by the promise of publicity and financial security, the group joins the documentary crew on-site where Dianna, the team’s psychic, finds herself inexplicably drawn to the ruined castle on the hill above the great house. Their investigation gradually reveals evidence of a dark history of ritual magic at the house and provokes a terrifying confrontation with a supernatural entity of unimaginable power. Will a careless act by the increasingly angry and resentful Magnus place the lives of everyone present in peril, despite their precautions? Everything has consequences, and nothing is what it seems.
