Dexter

An American crime thriller that follows Dexter Morgan (Michael C. Hall), a charming Miami forensic expert specializing in blood spatter analysis. However, he has a dark secret: he is also a serial killer who only targets criminals who have escaped justice. As a child, Dexter experienced severe trauma before being adopted by police officer Harry Morgan (James Remar), who taught him the "Code of Harry"—a strict set of rules that allow him to kill while avoiding capture. His sister, Debra (Jennifer Carpenter), a Miami police detective, remains unaware of his double life. As Dexter continues his hunt for criminals, his carefully constructed world starts to unravel under the weight of personal and professional threats.
