March, 1942. 90-pound weakling Steve Rogers doggedly attempts to enlist in the army, only to be repeatedly classified 4F. Rogers' determination and decency come to the attention of Dr. Abraham Erskine of the Strategic Scientific Reserve. Rogers is the first test subject for Erskine's super-soldier serum, which transforms him utterly. When the program is abruptly ended, Rogers becomes Captain America--touring America to sell war bonds.
