Lila, an agoraphobic poet, lives in a secluded Victorian house. Her husband Samuel, who is only vaguely aware of the demons that haunt his troubled wife, does his best to quietly support her.
One morning Lila sees on her usually desolate driveway a strangely familiar fellow, Barrington. The charming but subtly malevolent character returns each day, gradually gaining control of Lila during his increasingly disturbing visits. Under Barrington's enigmatic spell, Lila begins to mentally and physically deteriorate. As she weakens, Barrington grows stronger, and his genial manner soon fades into menacing obsession as he draws Lila away from Samuel and forces her into a terrifying showdown with her darkest fears.
