Patrick Gibson stars in the prequel series

In the beginning there was blood.

That’s the line from the first trailer for “Dexter: Original Sin,” in which a forensics student transforms into the serial killer we know and love from the popular Showtime series “Dexter.”

Patrick Gibson plays young Dexter in this prequel series, coming to Paramount+ with Showtime next month, the origin story of how Gibson becomes Michael C. Hall’s Dexter Morgan.

The trailer for the 10-part series shows Hall’s Dexter lying on his deathbed, his life flashing before his eyes. He reveals a colorful Miami and how Dexter’s father, played by Christian Slater, talks him into a life of murder, killing only the bad guys and making sure he never gets caught.

Here’s the official logline: “‘Dexter: Original Sin’ is set in 1991 Miami and follows Dexter (Patrick Gibson) on his journey from student to avenging serial killer. When his bloodthirsty urges can no longer be ignored, Dexter must learn to channel his inner darkness. Under the guidance of his father Harry (Christian Slater), he adopts a code designed to help him find and kill people who deserve to be excluded from society, without becoming a target for law enforcement. This is particularly challenging for young Dexter as he begins a forensic internship with the Miami Metro Police Department.”

“Dexter: Original Sin” also stars Molly Brown, Christina Milian, James Martinez, Alex Shimizu, Reno Wilson, special guest star Sarah Michelle Gellar and Patrick Dempsey. Michael C. Hall returns to perform the iconic inner monologue inside Dexter Morgan’s head.

The series is executive produced by Clyde Phillips and produced by SHOWTIME Studios and Counterpart Studios. Executive producers also include Scott Reynolds, Hall, Mary Leah Sutton, Tony Hernandez and Lilly Burns. The series is produced by Robert Lloyd Lewis (“The Lincoln Lawyer”). Michael Lehmann (“Heathers”) serves as executive producer.

For Showtime Studios, the series is creatively overseen by Gary Levine and Urooj Sharif, while production is overseen by Tara Power. The series is distributed by Paramount Global Content Distribution outside of the Paramount+ markets.

We last saw Dexter Morgan on screen in 2021’s Dexter: New Blood, which saw Hall reprising the role eight years after the end of the original series, which ran on Showtime from 2006 to 2013.

“Original Sin” will premiere on Paramount+ with Showtime for on-demand streaming on December 13th (if you have the Showtime plan) and also on linear on Sunday, December 15th at 10pm ET/US Showtime channel broadcast. PT.
