‘Dexter’ Season 8 Trailer: Debra Hits Rock Bottom, Dex Finds a New Foe (Video)

Dexter's life is made even more complicated by the arrival of a psychopath expert in season 8 trailer

Showtime's killer hit drama "Dexter" returns for its eighth and final season on June 30, and it looks like Debra, the titular serial killer's sister, is heading for hard times.

In a new trailer released for the series, Debra (Jennifer Carpenter), who last season got further drawn into Dexter's world with the killing of Maria LaGuerta, engages in all sorts of self-destructive behavior. Sniffing coke? Yep. Hooking up with a skeevy dude? Uh-huh. Getting arrested for DUI? Oh, goodness, yes…

Meanwhile, Dexter finds himself with a new problem in the form of Dr. Evelyn Vogel (Charlotte Rampling), an expert on psychopaths who blows into town and could spell trouble for Dex because, well, duh.
