The footage opens with Captain America, Black Widow, and Falcon dealing with Crossbones as the villain attempts to blow up a truck. During the fight, Crossbones tosses a magnetic explosive at Cap’s shield, and the hero throws it into the air so that the explosion avoids the crowd. Crossbones removes his mask and reveals his scarred face, turning to Cap and saying, "He remembered you, you know. You're little pal Bucky." The footage then cut to the scene during the credits of Ant-Man, where Cap and Falcon are talking to Bucky. Bucky tells Cap that he remembers his mom’s name was Sarah, and that he used to stuff newspapers in his shows. Cap smiles, knowing that some trace of his old friend is still in there.
We then see General Ross (William Hurt, reprising his role from Edward Norton’s Incredible Hulk) telling Cap how the country owes him an impossible debt, but that for some he's not a hero now but a vigilante. Cut to shots of Cap and Tony talking about what comes next, that Tony says how they're operating with oversight so how does that make them different from villains? "That's what this is about to you? Protection?" says Cap. While continuing to argue, Iron Man tells Cap, "Sometimes I want to punch you in your perfect teeth."
The footage then rolls into quick shots of the heroes delivering some pretty great lines. "In this job, you try to save everybody you can. Sometimes that doesn't mean everybody," say a stoic Captain America. Black Widow and Hawkeye, caught on opposite sides of the Civil War, are about to fight. "We're still friends right?" Black Widow asks. "Depends on how hard you hit me," Hawkeye replies. The footage ended with Hawkeye opening a van, revealing Paul Rudd's Ant-Man. He's absolutely starstruck by Captain America. He's shaking as he meets him, and fumbles the greeting. "You know a lot of super people, so thinks for thanking of me."
