After a terrible accident in Lagos with civilian casualties (on top of the events in Age of Ultron), Tony Stark and the UN come up with a charter for the Avengers. A charter that would make them answer to the UN and only be deployed where the UN deems necessary. Most of the members sign the form, except Cap, Falcon and Scarlet Witch. When there is a bombing at a UN meeting, the world begins a massive manhunt for the Winter Soldier. We get to see a bit of Winter Soldier’s 90s career with Hydra when he goes after a couple in a car and retrieves something that looks like the Super Soldier formula.
The military going after Bucky are given the orders to shoot to kill. Cap is most definitely against this and attempts to bring him in alive. Firmly putting him against the world governments, Tony Stark, and the other Avengers. Plus Black Panther. Unfortunately, T’Chala’s father was killed in the UN bombing. With this, we get Black Panther also going after Bucky.
We get a nice little chase sequence that ends with Bucky, Cap, Falcon and Black Panther being brought into custody. Zemo makes his way in and activates some Hydra programming left in Bucky. Zemo slips out and Bucky escapes after giving Zemo a debriefing. Cap and Falcon also make it out in pursuit of Bucky.
As a result of this, Iron Man and Cap begin recruiting among their friends for a showdown. Giving us the Marvel Cinematic Universe introduction of Spider-Man.
TL;DR Go see it. This is how you do a superhero movie with a lot of characters in it.
