After his father's death, Kale Brecht becomes a sullen, withdrawn, and troubled young man. He finds himself under a court-ordered sentence of house arrest after a run in with the law. His mother, Julie, works night and day to support herself and her son, only to be met with Kale's indifference and lethargy. As the walls of his house begin to close in on Kale, he turns into a voyeur as his interests turn outside the windows of his suburban home towards those of his neighbors. Slowly, Kale begins to suspect his neighbor is a serial killer.
