When the experiment unexpectedly transforms Peggy instead of its intended candidate, she becomes Captain Carter, an unstoppable symbol of hope for the Allied forces. Alongside the armored HYDRA Stomper, a team of Allied commandos, and legendary heroes from around the globe, Peggy wages war against HYDRA, led by the ruthless Red Skull, whose obsession with ancient power threatens not only the outcome of the war but the future of the entire world. As Peggy embraces her new role, she learns that true heroism is measured not by strength alone, but by the willingness to sacrifice everything for others.
