Steve Rogers (Captain America) is drawn into a violent clash when a neo-Nazi rally escalates and anti-hate protesters respond. Meanwhile, at S.H.I.E.L.D. headquarters a mysterious creature previously contained breaks loose — tying back to earlier villainous experiments. Amid personal and patriotic stakes, Rogers delivers an urgent defense of freedom and the memory of the Holocaust, confronting the rising wave of hate speech and white-supremacist rhetoric.
