The team of fearless Avengers, led by the famous Captain America, is involved in some very unpleasant incident of an international character. What has happened is forcing the government to seriously think about how to make people with non-standard talents behave in accordance with certain rules. These thoughts lead the officials to the conclusion that it is necessary to oblige all superheroes to legalize themselves. Now the brave heroes of the film "The First Avenger: Confrontation" need to report in the shortest possible time about their capabilities and in the future work only on official government organizations. Steve Rogers and a group of followers who follow him upset the accepted law to the depths of their hearts. They see in it a direct violation of their rights and a mockery of everything they are used to believe in. But Tony Stark and his supporters regard the law as absolutely right, they support it in every possible way, which inevitably provokes a split among the Avengers, so a full-fledged war begins between the conflicting parties. In this turbulent time for the heroes appears the enigmatic Baron Zemo, who intends to use the opposition of superheroes for his own mercenary purposes.
