'Dexter' Final Episodes Preview: The Walls Are Closing In (VIDEO)

There are only three episodes left in the final season of "Dexter," and the walls are closing in on the Morgan family.

In this final episodes preview video from Showtime, Dexter tells Deb about his plan to flee to Argentina with Hannah. But he has one person left to take care of before he can: Oliver Saxon, aka The Brain Surgeon. And it doesn't look like he'll go down easily. Will Dexter's family get stuck in the crossfire?

It all comes to an end on Sunday, Sept. 22 on Showtime.

"Dexter" airs Sunday nights at 9 p.m. ET on Showtime.
