It portrays a young Catholic woman, just beginning her college experience in an unfamiliar place. The movie might have shown us someone truly terrible, perhaps even a stalker. The setting on the edge of town creates a wonderfully dark and unsettling beauty; it’s strangely quiet and still. There's a palpable sense of unease as this person starts to make their presence known through things like silent phone calls and doorknobs being rattled. Then, unexpectedly, the story takes a sharp turn into some genuinely frightening territory. **Definitely not for those who are easily frightened.**
