With just 17 days remaining until the July 20 opening of The Dark Knight Rises, Warner Bros. has updated the Batman film's official site with some high resolution versions of images we've seen throughout the promotional campaign along with some brand new ones as well. Additionally, we've finally got an official plot synopsis and runtime for the eagerly anticipated but extremely enigmatic sequel.

Warner Bros. Pictures' and Legendary Pictures' "The Dark Knight Rises" is the epic conclusion to filmmaker Christopher Nolan's Batman trilogy.

It has been eight years since Batman vanished into the night, turning, in that instant, from hero to fugitive. Assuming the blame for the death of D.A. Harvey Dent, the Dark Knight sacrificed everything for what he and Commissioner Gordon both hoped was the greater good. For a time the lie worked, as criminal activity in Gotham City was crushed under the weight of the anti-crime Dent Act.

But everything will change with the arrival of a cunning cat burglar with a mysterious agenda. Far more dangerous, however, is the emergence of Bane, a masked terrorist whose ruthless plans for Gotham drive Bruce out of his self-imposed exile. But even if he dons the cape and cowl again, Batman may be no match for Bane.
