The leader of the international squad of aviators called The Blackhawks -- Polish pilot Janos Prohaska, himself called Blackhawk -- is on American soil and in trouble. Accused of Communist
leanings, he stumbles across a plot to overthrow the U.S. government and bomb New York City being concocted by former Nazis out for revenge. As he struggles to stop them and clear his name, he
runs afoul of a beautiful Russian scientist and reunites in battle with his international comrades.
