Dexter Morgan, Miami Metro Police Department blood spatter analyst, has a double life. When he's not helping the Homicide division solving murders, he spends his time hunting and killing bad guys that slip through the justice system. He spends his sun-drenched days solving crimes - and moonlit nights committing them. But not to worry, our cool-blooded Dexter doesn't kill just anyone. He reserves his homicidal hobbies to taking only the lives of other killers.
