The Good Child (S04E18)

Rachel Coburn (Gaby Hoffman) is not happy with her life, which appears on the surface to be perfect – loving parents, a nice house. But she's been meeting with an older, married man named Trevor Osborn (John Shea) and she's living with secrets. Her life is turned upside down when her parents, Camille (Lizbeth MacKay) and Dennis (Michael Hobbs) are brutally executed, and it is discovered that the Coburns are really the Meisners from Buffalo. They are in witness protection after Dennis cooperated in a major sting that resulted in convictions and serious jail time for the Marinko brothers. (iTunes)
