Arnim Zola is reporting to the Red Skull that all is going
according to schedule when his rebel daughter Jet Black arrives to oppose him.
Zola reveals that she has been his pawn all along, that even her turning
against him was part of his plan. Falcon then enters the room and carries Jet
and Zola through a high window; Sam scoops up Jet as the villain plummets to
the street below. Sam contacts Steve Rogers to tell him that they found Sharon Carter
alive in the tower—Steve calls Ian Rogers who confirms that she raised him as a
mother after Captain America departed Dimension Z. Falcon battles Zola while
they struggle over Jet’s loyalties. Ian rescues Sharon from the tower but they learn Zola’s
hidden plot: there is a bomb set to destroy the Avengers and all of New York. When Sam
learns that Zola can trigger the bomb with his telepathic antennae he has
Redwing rip it off. Big mistake as the destruction of his antennae merely sets
the bomb to detonate in 30 seconds. Iron Man tries to stop it but his Unvenger
counterpart drags him down. Falcon seizes the bomb and, with a word of farewell
to Steve, flies the bomb high into the stratosphere where it explodes….
Hulk and Thor also appear but couldn't be worked into the synopsis.
