Behind the normal door of a normal house, in a normal street, two men are slowly driving each other insane. One of them is a psychopath. The father: Mr Todd is at his wits end. He's been robbed of his job as a tax inspector and is now stuck at home . . . with him. Frustrated. Lonely. Angry. Really angry. The son: Adrian has no job, no friends. He is at home all day, obsessively chopping vegetables and tap-tap-tapping on his computer. And he's getting worse, disappearing for hours at a time, sneaking off to who-knows-where. The unholy spirit: In the safety of suburbia, one man has developed a taste for killing. And he'll kill again.
