We have a new exclusive sneak peek from Dexter: Original Sin to share.

Watch as Dexter joins Miami Metro and begins the first day of the rest of his life. But first a pep talk from Harry, and introductions to some iconic Dexter characters.

Via paramount+ — He’s smart, he’s good looking, and he’s got a great sense of humor. He’s Dexter Morgan, everyone’s favorite serial killer.

As a Miami forensics expert, he spends his days solving crimes, and nights committing them. But Dexter lives by a strict code of honor that is both his saving grace and lifelong burden. Torn between his deadly compulsion and his desire for true happiness, Dexter is a man in profound conflict with the world and himself.

Set in 1991 Miami, Dexter: Original Sin takes us back in time as Dexter (Patrick Gibson) transitions from student to avenging serial killer. When his bloodthirsty urges can’t be ignored any longer, Dexter must learn to channel his inner darkness.

With the guidance of his father, Harry (Slater), he adopts a Code designed to help him find and kill people who deserve to be eliminated from society without getting on law enforcement’s radar. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.

The new series also stars Christina Milian, James Martinez, Alex Shimizu and Reno Wilson. Michael C. Hall returns to voice the iconic inner monologue in Dexter Morgan’s head.  

Sarah Michelle Gellar also guests as Tanya Martin.

Stream Dexter: Original Sin ahead of time on December 13th on the Paramount+ with SHOWTIME plan, or in its regular debut slot on Sunday, December 15 at 10 p.m. EST / PST on Paramount+.
