During the day, Dexter Morgan is a jovial employee in the Miami Metropolitan Police Depoartment's crime lab, but his meticulously crafted life masks his true nature. In reality Dexter is a disciplined and murderous psychopath (a self-admitted "monster"), and he slakes his bloodlust at night by carefully killing the serial killers he tracks down during the day.
