Watch: Deb Freaks & 'Dexter' Dodges In New Trailer For Season 7

nullAfter spinning its wheels for the last couple of seasons, "Dexter" ended season six with a helluva cliffhanger, with the lead serial killer's cop sister literally catching him in the act. As we already know, season seven will begin right where we left off (in case you missed it, you can watch the first two minutes of the first episode here). Now, a new trailer has dropped for the upcoming season, and it appears that Dexter will be playing a game of cat and mouse to keep the depths of his crimes under wraps.

It looks like the stakes are going to be raised in a major way, as the central subject of the new run of episodes appears not be a new criminal to track down, but Dexter himself. It seems that Deb is like a dog with a bone about what she saw, going back to investigate both the Ice Truck Killer case and Bay Harbor Butcher murders and starting to see some eerie parallels with what she witnessed Dexter doing in the church. But of course, her brother won't go down without a fight, and it seems even his sister is fair game as a victim if it means keeping him out of jail or worse.

Compelling stuff indeed, and we're really curious to see where this season goes. "Dexter" kicks off on Showtime on September 30th. [Dark Horizons]
