Char is given an assignment to work as a riveter at Douglas Aircraft. She has a partner, FBI agent Ellen Frazer.   They are to stop the Nazi saboteurs who are bent on hampering the U S and Allies in their attempt to defeat Germany.

The Woman In the Wing chronicles the story of the brave and determined women who flew and transported planes as the Womens Air Force Service Pilots and of the "Rosie the Riveters" who worked to build the planes. It is a suspenseful mystery with the Nazis, murder and sabotage.  But it also describes the struggle and hardship the women had to endure to begin an active role in World War II.  Many men wanted to see the program fail, believing that flying was not "a woman's pursuit."

There are references at the end of the book about the role of American women serving in World War II for any reader who wants to know more.
