In 1942, Steve Rogers (Chris Evans) is deemed too physically unfit to enlist in the U.S. Army and fight the Nazis in World War II. Volunteering instead for Project: Rebirth, a secret military operation, he is physically transformed into a super-soldier dubbed Captain America. With sidekick Bucky Barnes, he fights the Red Skull (Hugo Weaving), Hitler's treacherous head of advanced weaponry, whose own plan for world domination involves a seemingly magical object known as the Tesseract.
"Captain America: The First Avenger" will focus on the early days of the Marvel Universe when Steve Rogers (Chris Evans) volunteers to participate in an experimental program that turns him into the Super Soldier known as Captain America. As Captain America, Rogers joins forces with Bucky Barnes (Sebastian Stan) and Peggy Carter (Hayley Atwell) to wage war on the evil HYDRA organization, led by the villainous Red Skull (Hugo Weaving.)
