War puts courage and love to the test. It's 1939, a lone Spitfire roars over her family home, and Ilona Lowe, entranced by its grace and power, finally knows her place in the fight against Hitler. She joins the Women's Auxiliary Air Force, is stationed at RAF Catterick and embarks on an all-too-brief love affair with a Bleinheim bomber pilot who is killed during the Battle of Britain. Heartbroken, but determined to carry on, Ilona returns to active duty where she encounters Francis Robson. He's arrogant-some would even say reckless-and another pilot. Yet he's worth the risk. Their love isn't easy. Francis harbors jealousy about her former lover while Ilona's posting at an RAF bomber base feeds her nightmares about Francis' safety. She can see the escalation of stakes as his missions grow ever more dangerous, the enemy more desperate. Ilona must put her courage to the test because she knows that loving Francis means letting him let him fight on, regardless of the terrible price they both may pay.
