The eighth and final season of Dexter finds Dexter Morgan's (Michael C. Hall) carefully constructed world continuing to fall apart at the seams following the death of Lt. LaGuerta at the hands of Dexter's own sister Debra (Jennifer Carpenter). While Debra languishes from remorse, Dexter meets a psychopathologist who appears to understand the code of ethics that have served as motive for Dexter in his storied alter-ego as a serial killer.

Nate Ford (Timothy Hutton), an expert thief who was once an insurance investigator, leads a down-and-out crew of people eager to get even with the rich and powerful individuals that contributed to their own financial ruin. Relationships among the group continue to evolve, while Nate struggles to come to terms with his place in the world. Elsewhere, Interpol agent Jim Sterling (Mark Sheppard) dedicates himself to apprehending Nate and putting a stop to his exploits.
