The Showtime series "Dexter" follows a Miami cop who doubles as a serial killer. All of his victims are chosen for a reason, however, as Dexter kills only those who deserve it. Dexter is stuck in the balance between disaster and media because while he must satisfy his urge to kill, he must also keep the media off his trail.
