Dexter: Original Sin S1

Twenty-year-old forensic intern Dexter Morgan is about to become everyone's favourite vigilante serial killer …

Showtime’s most streamed Original ever, the prequel series Dexter: Original Sin is set in Miami in 1991, 15 years before the start of the multiple-award-winning original series.

Irish Film and Television Award winner Patrick Gibson (The OA, Shadow and Bone) stars as the young Dexter, with Golden Globe winner Christian Slater as his father, Harry. The cast also includes Emmy nominee Patrick Dempsey (McDreamy from Grey’s Anatomy) and Emmy winner Sarah Michelle Gellar (aka Buffy the Vampire Slayer). Multiple-Emmy nominee Michael C Hall, the original Dexter, voices Dexter’s iconic inner monologue.
