It is 1941 and the world is in the throes of war. Steve Rogers wants to do his part and join America's armed forces, but the military rejects him because of his small stature. Finally, Steve gets his chance when he is accepted into an experimental program that turns him into a supersoldier called Captain America. Joining forces with Bucky Barnes and Peggy Carter, Captain America leads the fight against the Nazi-backed HYDRA organization.
