In 1941 America, Kay and her husband are happy enough until he enlists after Pearl Harbor. Against his wishes, she takes a job at the local aircraft plant where she meets Hazel, the singer from across the way. The two soon become firm friends and with the other girls become increasingly expert workers. As the war drags on, Kay finally dates her trumpet-playing foreman and life gets more complicated.
A detailed investigation into the political and economic interests that, since the beginning of the 20th century, have pulled the strings of the arms trade, hidden in the shadows, feeding the shameful corruption of politicians and government officials and promoting a state of permanent war throughout the world, while they cynically asked for a lasting and universal peace.
