1941. The German war machine has crushed all of Europe-only England holds fast. To force a surrender, the German Luftwaffe bombs cities and villages the length of the country. As the battle rages, Britain is in desperate need to put more pilots in the air.

To free up more men a new unit is formed: The Ack Ack Girls. These special teams of courageous women will now fight in the anti-aircraft stations. Determined to be part of the effort, Ava Armstrong, volunteers for one of the special teams.

Her unit just happens to be located near an RAF airfield teaming with pilots. Sparks fly, and not just from artillery, when Ava crosses paths with Chris Fairfield, a handsome and cocky pilot stationed there. But nothing is easy in time of war, not even love.
