In the 1980s, twelve-year-old Matthew Cooper is experiencing some strange and terrifying events at an old rental house where he and his family have recently moved. TVs and radios click on and off in the middle of the night. Odd shapes are drawn in the foggy glass of a bathroom mirror. No one can explain these things, and as their encounters become more bizarre and intense, Matthew's family slowly descends into darkness and paranoia, the psychological horror becoming more of a threat than what might be lurking behind their walls.
