A young Swedish woman, Hanna, comes home to her apartment for the evening. After a rather foreboding conversation with one of her friends involving recent disappearances in the area, and an old Native American boarding school that was burned down, she settles in to a seemingly hum-drum close of day, and eventually goes to bed. Her slumbers don't last long however, and she wakes after a terrifying dream. Things take a horrifying turn for the worse as it becomes more apparent that someone - or something - has crept into her apartment.
