The explosively popular DEXTER® is back with a vengeance for a sixth season of startling suspense and unexpected twists. It's been a year since last season's shocking and heartbreaking conclusion, and mild mannered criminologist-cum-grisly serial killer Dexter Morgan has come to terms with who he is. But his existence is shattered when he crosses paths with an enemy unlike any he's faced before. A delusional religious zealot with unflinching convictions, this new adversary soon draws Dexter into a dangerous game that could well end in disaster.

Who is Dexter Morgan?

Dexter Morgan, Miami Metro Police Department blood spatter analyst, leads a double life. When he's not helping the homicide division solve murders, he satisfies his dark desires by hunting and killing bad guys who slip through the justice system, all the while following a strict code established for him by his father.
