Peggy Witherspoon, a mother of two daughters, has been widowed due to the war in Europe. She comes from a long line of US war heroes and, considering it her duty, joins the female pilots flying for the WASP (Women Airforce Service Pilots) in 1944. Most of Peggy's duties are safe and predictable as she ferries airplanes between factories and military bases, and she can be home nearly every night with her daughters. After being injured in combat, Army Air Corp Major Howie Berg is stationed at Bolling Field in Washington, DC, while he continues to recover. As the new reporting officer for the WASP, his first encounter with Peggy is when she disobeys one of his direct orders. While flying a routine load of cargo to Cuba, Peggy learns about three US soldiers being held captive there. Furious that no rescue is planned due to Cuba's status as an American ally, Peggy and two of her fellow WASPs devise a secret rescue mission. However, if something goes wrong, she and the others will have no backup. Will Peggy go against orders to help the men - even risk her own life?
