Dexter: Original Sin

In 1991, Dexter Morgan, portrayed by Patrick Gibson, begins his training as a forensic specialist at the Miami Metro Police Department. As he embraces dual lives—both skilled technician and vengeful serial killer—the dark urges that threaten to consume him must be contained. Guided by mentor Harry (portrayed by Christian Slater),who is also Dexter’s foster father, Dexter follows the Code, a set of rules designed to enable him to hunt down other killers without drawing attention from authorities.
