UPDATED TO SEASON 5 FINALE
Dexter is an American drama about a serial killer who works as a blood splatter analyst for the Miami Metro Police Department. Something of a vigilante, Dexter follows a Code (sanctioned by his late former detective father, Harry) where he must only kill those who have killed and have the capacity to kill again. This list comprises of all the individuals who are opposed to Dexter, whether they are a serial killer, a law enforcer or a minor criminal that breaks the code.
Dexter is the product of a traumatic event when he was just a baby. His mother, who was a police informant, was hacked up with a chainsaw in a shipping contrainer by three criminals. Dexter was left unharmed but had to sit in the container in a pool of blood for 2 days before Harry found him.
Harry took Dexter home with him and adopted him. As he grew, Harry started to notice many aspects of Dexter's personality which made him suspect he had urges to kill. Harry deemed it necessary to train Dexter to suppress these urges and when that failed, he trained him to kill and get away with it. Harry devised The Code to give Dexter's activities a 'moral' goal while still being able to live a 'normal' life.
Dexter feels a shallow range of emotion and rarely expresses the right one at the right time. He finds his relationships with other people hard but with practice he has managed to create a 'personality' which most of his colleagues endear. His step-sister, Deb, who he feels closest to sets him up with an emotionally and physically abused woman; Rita. Rita is a mother of two who is so insecure that she does not make any advancements on their relationship which suits Dexter just perfectly but as the series evolves so does Dexter and his relationships.
