"Dexter: Original Sin" Unveils Premiere Date

The “Dexter” prequel series, “Dexter: Original Sin” has set its premiere for December 13 via streaming and on-demand for Paramount+ with Showtime subscribers and internationally; linear will premiere two days later. 

Set 15 years before the events of “Dexter,” the 10-episode thriller stars Christian Slater as Harry Morgan, Patrick Gibson as Dexter Morgan, and Molly Brown as Debra Morgan.

The official synopsis reads: “Set in 1991 Miami, ‘Dexter: Original Sin’ follows Dexter (Gibson) as he 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 enforcements’ radar. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.”

The original “Dexter” series aired on Showtime from 2006 to 2013 and starred Hall in the titular role and Jennifer Carpenter as Morgan.

“I’m a killer but I wasn’t born this way; I was made,” TV’s original Dexter, Michael C. Hall, says in a voiceover in a teaser clip. Hall will narrate the inner monologue inside the serial killer-in-training’s head in the prequel.

Clyde Phillips, the original showrunner and executive producer on “Dexter,” returns in that role for “Original Sin.”
