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...

In season five, Dexter goes from happily married husband to guilt-ridden single dad. How will it affect his ability to maintain an average-guy facade while satisfying his need to kill?

Dexter is back with a new take on taking life. He is ready to put the past behind him, until a high-profile case puts him in the sights of powerful Assistant DA Miguel Prado, and the pressure might be too great for even Dexter to hack.

An elite team of detectives investigates smuggling and trafficking; three students participating in an Internet computer game get involved in an investigation of a serial killer; a criminal profiler tries to get inside a serial killer's mind in order to stop him.
