Set in Miami, the series centers on Dexter Morgan, a forensic technician specializing in blood spatter analysis for the Miami Metro Police Department. BUT Dexter leads a secret parallel life as a vigilante serial killer, hunting down murderers inadequately punished by the justice system due to corruption or legal technicalities. The show’s first season was derived from the novel Darkly Dreaming Dexter, the first in a series of novels by Jeff Lindsay. The first four seasons were widely praised, award-winning and it’s season finale was broadcast to a record-breaking audience. Although popularity dropped off, there is still a cult audience for numerous spin-off’s and prequels.
