Sunday, June 30th will mark the beginning of the end for "Dexter" -- Showtime made it official last month that the eighth season of its popular serial killer drama will also be its last.

The premium network has released a trailer for the final season showing Dexter's (Michael C. Hall) relationship with his adoptive sister Deb (Jennifer Carpenter) in shambles and a new potential foe on the horizon -- an expert on psychopathy played by the regal Charlotte Rampling. Will Dexter survive his show, or go down with it? The endgame promises to be interesting.
