When the past refuses to stay buried, three people will discover that the American dream can be a nightmare ... Megan is a suburban soccer mom who once upon a time walked on the wild side. Now she's got two kids, a perfect husband, a house with a picket fence and a growing sense of dissatisfaction. Ray used to be a talented documentary photographer, but at the age of 40 he finds himself in a dead-end job posing as a paparazzo pandering to celebrity-obsessed rich kids. Broome is a detective who can't let go of a cold case - the disappearance of a local husband and father 17 years ago. As the terrible consequences of long-ago events collide in the present, three people - living lives they never wanted, hiding secrets that not even those closest to them would ever suspect - will come to realise that the past never truly fades away. And as each confronts the dark side of the American dream - the boredom of suburban life, the thrill of temptation, the desperation that can lurk behind even the prettiest facades - they will discover the hard truth that the line between one kind of life and another can be as whisper thin as a heartbeat.
