We saw a complete scene, which was very reminiscent of one of the best moments from Drive. Captain America gets into an elevator at SHIELD headquarters, and then Crossbones (Frank Grillo) gets in with him, with a couple of other guys, all heading for Operations. They're talking about spy stuff, but Cap notices they have their guns out. And then a bunch of guys in suits get in, heading for Operations. And there's something hinky about them, too. Someone says "fuck you contract," randomly.
Even more guys get into the elevator and say "Records." And then Cap is surrounded by a ton of guys. In a small glass elevator. He's massively outnumbered in a tiny space.
Cap says, "Before we get started, does anyone want to get out?" Nobody does. They attack, and he hits emergency stop, and all of these guys are trying to kill him at once. There's a wristband which is magnetized, and it gets attached to the wall of the elevator, and then Cap's wrist is stuck in it so he's fighting with one hand trapped. He basically kicks the hell out of all these guys, using their own weapons against them. It's amazing. Eventually Captain America gets his wrist free so he can fight two-handed.
At last, it's just Cap and Crossbones, who says "it's nothing personal." He tases Cap over and over again, and Cap just keeps coming. Cap throws him into the ceiling. Cap is standing in the elevator, surrounded by prone bodies and broken glass, and he reaches down to grab his shield, with a loud clang.
