‘Dexter’ Season 7 Trailer Give Us the Chills…And the Desire to Buy Premium Cable (VIDEO)

It's hard to believe Dexter has been cleaning up the streets of Miami with vigilante homicide for almost seven years already. And in all that time no one has learned of his secret and lived to tell the tale. But from the new official trailer for this fall's season, it looks like that might all finally be changing. The chilling look offers us a glimpse of an epic brother vs. sister battle that makes us want to call up our big brothers and thank them for not ever coming at us with a cleaver.

Dexter returns to Showtime on Sunday, September 30th.
