As you know, there will be two main teams/sides: Team Captain America and Team Iron Man. When public sentiment turns against superheroes, the United States government uses the opportunity to install a governing body to determine when to enlist the services of the team. Captain America isn't in favor of this as the governing body could do more harm than good as it has the power to determine who is a hero and who is a villain.
Joining Captain America (Chris Evans) on his crusade will be Hawkeye (Jeremy Renner), Falcon (Anthony Mackie), Scarlet Witch (Elizabeth Olsen), Ant-Man (Paul Rudd) and The Winter Soldier (Sebastian Stan).
While Iron Man (Robert Downey Jr.) will oppose them with The Vision (Paul Bettany), Spider-Man (Tom Holland), Black Widow (Scarlett Johansson) and War Machine (Don Cheadle).
El Mayimbe added this plot tease: "Can you guess which Avenger might be a double agent?"
Captain America: Civil War picks up where Avengers: Age of Ultron left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.
Captain America: Civil War opens in theaters May 6, 2016.
