Iron Man, Captain America, and Black Widow stand in a dimly lit, circular chamber, then run forward in unison through a corridor with large windows, before Iron Man stumbles and falls to his knees as Captain America and Black Widow continue running. The scene shifts to Captain America shouting with his shield raised, then cuts to a man in a grey t-shirt standing in a dilapidated room, followed by a shot of a man and a woman sitting in a modern, sterile room, looking concerned.
