Set photos from Captain America 2: The Winter Soldier have leaked online and they show Chris Evans as Captain America and Scarlett Johansson as Black Widow in full costume. Both actors appear to be attached to a harness system, presumably to facilitate some high-flying stunt work.

The images don't give up much in the way of Captain America 2 plot spoilers. We can safely infer that somewhere in the movie, there will be a scene featuring the First Avenger and Black Widow creeping through a warehouse somewhere, but that's about all we can glean from the photos.
