What will Dexter: Original Sin be about?

Dexter: Original Sinwill take place in 1991, fifteen years before the events ofDexter.The official logline forDexter: Original Sinstates that the prequel series:

follows Dexter (Gibson) as he transitions from student to avenging serial killer. When his bloodthirsty urges can’t be ignored any longer, Dexter must learn to channel his inner darkness. With the guidance of his father, Harry (Slater), he adopts a Code designed to help him find and kill people who deserve to be eliminated from society without getting on law enforcement’s radar. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.

The originalDexterseries did feature some intriguing flashback sequences to the early days of the serial killer with a code, proving there are plenty of stories to explore about this iconic character as he becomes a full-fledged killer. It will also be a good opportunity to explore the character of Dexter’s adoptive father, Harry Morgan, as he balances his job as a detective in the Miami Metro Police Department, with the complexities of his adopted son’s murderous urges as he forms the ‘code’ which became such a vital part of the original show.

It seems a good point forDexter’s prequel seriesto begin with the serial killer’s entry into the forensics department of Miami Metro as an intern, while he earmarks victims for his legendary kill table.It remains unclear from the official logline for the prequel series, as to what Debra Morgan will be doing during this timeline, but it will likely see her catch the bug for police work and join Miami Metro as well.Other characters, such as Tom Matthews, who was a trusted ally to Harry Morgan in the department, will likely appear in the upcoming series, and maybe the spin-off series will chart the origins of Dexter’s disturbed lab partner, Vince Massuka, as he perfected his famous filthy laugh.
