The narrative centers on the Sokovia Accords, an international treaty designed to regulate the actions of the Avengers following significant casualties and destruction during their previous missions. Governments worldwide advocate for oversight to prevent further unintended consequences caused by superhero interventions. However, this initiative sparks deep divisions within the Avengers. Steve Rogers, known as Captain America (portrayed by Chris Evans), emphasizes the importance of individual freedom and personal choice, arguing against external control. In contrast, Tony Stark, also known as Iron Man (played by Robert Downey Jr.), supports the need for accountability and regulation to mitigate future disasters. This ideological conflict escalates into a full-blown civil war, pitting former allies against each other and fracturing the unity of the team. The story explores themes of responsibility, autonomy, and the ethical dilemmas faced by individuals with extraordinary abilities.
