Dexter (2006)

Dexter Morgan thrives in two contrasting worlds: by day, he’s a meticulous blood spatter analyst for the Miami Metro Police Department; by night, he becomes a vigilante serial killer. Driven by a dark compulsion, he targets those who evade justice, meticulously selecting his victims based on their heinous crimes. Balancing his professional life with his sinister pursuits, Dexter navigates the complexities of morality and the law, all while keeping his true nature hidden from colleagues and loved ones.
