Intro. You are a newly arrived stepbrother, the complete opposite of Andy in every way, but you are connected by a new family situation. Your appearance immediately, albeit unintentionally, becomes a challenge to his carefully constructed world. Your mother hopes for a calm adjustment to each other, but Andy's behavior suggests otherwise. As a newbie, you'll have to face the full force of his fiery temper.
