In 1941, Steve Rogers is the test subject of the top secret Operation: Rebirth. The experiment is a complete success with Steve Rogers' physiognomy suddenly raised to the maximum human potential. Unfortunately, at that triumph, the lead scientist was immediately assassinated by a Nazi spy and the formula was irretrievably lost. The US government, aware that war with Nazi Germany was imminent, decided to make the most of their resource by appointing Rogers as their propaganda symbol/government agent, Captain America. Armed only with an indestructible shield, we follow his adventures in World War II with his sidekick, Bucky. In addition, we follow his further adventures after he reemerges in contemporary times out of suspended animation to face all the threats to America and its ideals.
