Tony Stark, aka Iron Man (Robert Downey Jr), reluctantly submits, telling his compatriots: “I’m doing what has to be done to stave off something worse.”
Steve Rogers, aka Captain America (Chris Evans) refuses to sign, fearful of the consequences of the Avengers relinquishing their independence.
The gulf between Stark and Rogers forces the remaining Avengers to take sides.
A battle royale between the two factions unfolds.
