Steve Rogers (Chris Evans) is a humble, patriotic kid from Brooklyn. He wants nothing more than serve his country in World War II. Alas, he is a frail and sickly youth whose attempts to enlist in the United Stated armed forces have been unsuccessful. His fortunes change when he attends the Modern Marvels of Tomorrow Exhibition with his friend Bucky (Sebastian Stan). While there, he makes one final attempt to enlist at a recruitment center. He then makes the acquaintance of Bavarian scientist Dr. Abraham Erksine (Stanley Tucci).
