Dexter receives a registered letter that informs him that his biological father has recently died. This comes as a shock, because Harry, Dexter's adoptive father, had told Dexter that his real father had died over 30 years ago. As Dexter takes off to reconnect to his shadowy past, Rita decides to come along to help him make it through the weekend. Then Debra and Rudy join them for the weekend at the dead bio-dad's house and things become even more awkward. Back in Miami, Doakes is involved in the questionable shooting of a middle-aged Haitian man. Internal Affairs investigates and Batista has to decide if he's going to tell the truth about the shooting, or back Doakes' untrue version of the actual incident.
