A troubled young man, Robert, leaves the big city and his ex-wife for the tranquility of a small town. He finds respite from his problems by secretly watching the normal domestic life of a woman he doesn't know through her kitchen window. When Jenny catches Robert in the act, she doesn't call the police. Instead she starts an affair with him, which has dire consequences when her boyfriend Greg finds out. Immediately suspicious of Robert, Greg makes it his mission to destroy him. But when a fight leaves Greg unconscious and missing, Robert discovers he is the number one suspect in a murder case that is slowly beginning to look like the ultimate set-up.
