Dexter's prequel series Original Sin will get underway in December, TVLine has learned. The drama, which follows the original show's central character during his teenage years, will premiere on Sunday, Dec. 15, on Paramount+ With Showtime; the episode will be available to stream two days earlier, on Friday, Dec. 13.

The spinoff is set in the 1990s and is centered on a younger version of the serial-killer character played by Michael C. Hall in the original series. (Hall will narrate the show, as well as star in another spinoff, Dexter: Resurrection.) Per Original Sin's official description, young Dexter is unable to control his "bloodthirsty urges" and must learn to "channel his inner darkness." (See the first photos from Original Sin here.)

In conjunction with the premiere date news, the network released the series' first teaser trailer, which you can watch above. "I am a killer, but I wasn't born this way. I was made -- by my history, by the people around me," Hall narrates as we watch flashes of Dexter's formative years. "They say it takes a village to raise a killer."

Patrick Gibson (Shadow and Bone) will play Dexter, with Molly Brown (Billions) as his sister Deb and Christian Slater (Mr. Robot) as his adoptive father, Harry. The cast also includes Sarah Michelle Gellar (Buffy the Vampire Slayer), Patrick Dempsey (Grey's Anatomy), James Martinez (Love, Victor), Christina Milian (Grandfathered), Alex Shimizu (The Blacklist) and Reno Wilson (Good Girls).
