Sam arrives at the GRC attack in his new Wakandan suit and introduces himself as Captain America. Batroc delays him inside the building while the Flag Smashers move officials into vehicles. Bucky and Sharon work on the ground as Sam pursues a helicopter carrying hostages. With help from a passenger who can fly, he gets them safely out of the hijacker's control. Walker joins the fight and chooses to help save a truckload of captives.
During the pursuit underground, Sharon confronts Karli and is revealed as the Power Broker. Sam still tries to reach Karli without fighting her, but she raises a gun and Sharon shoots her. Sam carries Karli's body outside and challenges the rescued officials to address the suffering behind her movement. Bucky and Walker help arrest the other Flag Smashers, whose transport is later destroyed in an explosion arranged through Zemo's butler. Valentina gives Walker a new suit and the name U.S. Agent.
Bucky finally tells Yori that he killed his son as the Winter Soldier, then returns his completed notebook to Dr. Raynor. Sam takes Isaiah and his grandson Elijah to the Captain America exhibit, where a statue and account of Isaiah's service now stand. Sam and Bucky join the Wilson family's gathering in Louisiana. Sharon receives her promised pardon, but her return to government work gives her a new opportunity: she calls a contact to offer access to its secrets and weapons.
