Nick Walsh is a broken, deeply cynical man. Since the violent deaths of his parents thirteen years earlier, he has been living alone in his childhood home in the suburban Midwest, drinking, drugging, and debauching himself into oblivion. He begins a campaign of spying on his neighbors via hidden cameras and microphones he has covertly installed in their houses. As he observes with amusement and disbelief all the strange, sad, and terrifying things that his neighbors do to themselves and to one another, and as he, in turn, learns that he is being stalked, he begins to slowly unravel the shocking truth about how and why his parents died.
