Watch: 'True Blood' Final Season Teaser, 'There's No One Left'

The premiere of the seventh and final season of "True Blood" is two months away, but HBO is getting the anticipation started with a new teaser trailer that hints at some big trouble in Louisiana.

In the trailer, a voiceover by Sookie lays out the plot of, presumably, the season's first episode and beyond. She tells of "an attack at the church tonight" and the speculation that the attack was carried out by the "sick vampires." Her narration is accompanied by images of a vampire feeding frenzy, dead bodies, deserted streets and "the good folks of this town" taking up arms, "turnin' on each other" and "acting like animals."

The trailer ends with Sookie whispering ominously, "There's no one left."

The teaser's apocalyptic imagery is clearly meant to evoke the feel of a certain zombie drama, but there's also an obvious link to the real-world events of the aftermath of Hurricane Katrina. In one shot, the words "FEMA HELP US" are scrawled in chalk on the pavement of a street, as Sookie's voiceover laments the failure of authorities to provide assistance.

"How can it be happening," she says, "in this country, in this day and age, that our government would leave us for dead?"

Season 7 of "True Blood" debuts on HBO on June 22.
