In this new series, fans will get to see Dexter’s evolution from childhood, where he emerges into a serial killer. The show will highlight Dexter (Patrick Gibson) and his dad Harry developing a system to find people who are a detriment to society so Dexter can kill them without law enforcement finding out, according to the synopsis.

The plot twist comes when Dexter gets an internship at the Miami Metro Police Department, and has to mask the other side of him, which is where Dempsey’s character comes in.

The star-studded cast also includes Molly Brown as Debra Morgan, James Martinez as Angel Batista, Christina Milian as Maria LaGuerta, Alex Shimizu as Vince Masuka and Reno Wilson as Bobby Watt.

This isn’t the only Dexter spinoff — in February 2023, the network confirmed a new version of the 2021 limited series Dexter: New Blood, which will follow Dexter’s son Harrison.

"The Dexter saga has been an undeniable creative and popular success for Showtime, both in its original, groundbreaking form and the record-setting Dexter:New Blood," McCarthy said in a press release shared with PEOPLE at the time. "The series is a rich foundation for other shows in the lane of complex, subversive antiheroes that Showtime has always done so brilliantly. Clyde is deep into compelling stories and characters that will satisfy the cravings of our multifaceted audience."

"It's a privilege to contemplate going even deeper with these complex and iconic characters – and the stories, themes and possibilities they inspire.

The original Dexter, which starred Emmy-winner Michael C. Hall, ran for eight season from 2006 to 2013. The series finale left Dexter in a new place in his life, seemingly working as a lumberjack after the death of his sister Debra (Jennifer Carpenter).
