A suburban wife and mother of two - with a dark and dangerous past. A promising photographer who now panders to celebrity-obsessed rich kids. A detective who can't let go of a cold case... Three people living lives they never wanted, hiding secrets that even those closest to them would never suspect, will find 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 discover the hard truth that the line between one kind of life and another can be a whisper as thin as a heartbeat.
