By day, Dexter Morgan is a mild-mannered blood-spatter analyst for the Miami Metro Police; by night, he is a meticulous serial killer who preys only on murderers who have escaped justice. Trained since childhood by his adoptive father to channel his homicidal urges through a strict moral code, Dexter hides his true nature behind a carefully rehearsed mask of normalcy. As he juggles relationships, colleagues, and his suspicious detective sister, each new hunt risks exposing the monster beneath. Darkly witty and psychologically gripping, the series dares the audience to root for a killer while probing the nature of identity and self-control.
