In 1942, Steve Rogers (Chris Evans) is deemed 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 (Sebastian Stan), 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.
