Dexter: Original Sin !!exclusive!! -

For years, fans of Dexter have wondered: How did a charming, blood-spatter analyst become a meticulous serial killer? After the controversial original series finale in 2013 and the mixed reception of Dexter: New Blood in 2021, Showtime is going back to the very beginning.
