When Michael Faraday and his ten-year-old son Grant meet the Langs, a vivacious, All-American family new to their suburban Washington neighbourhood, they quickly become friends. But as the two families become closer, Michael slowly starts to have misgivings about the gregarious Langs and after a little investigation, he discovers they are definitely not who they claim to be. Why has this seemingly innocent family come to Washington? And what is really going on in the house across the street? A tense political and psychological thriller, 'Arlington Road' weaves together the thematic strands of friendship and betrayal, suspicion and deceit, and the untrustworthiness of outward appearances.
