Elena Dunhoff and her younger brother Nathan are mediums-- people with the ability to connect to the other side and communicate with those who have passed. Their gift has never been much of a problem, and their appointment sheet is more blank than not, but when Nathan is filmed unknowingly during a session, and his face put on YouTube, Elena fears for her brother's safety. She hires a bodyguard, 21-year-old Wim Paschen, believing things will grow better. But is it really humans attacking their house? Or is it something less alive?
