It is 1943 and the quiet of Harrowbeer, in Devon, is disrupted by increased activity at the nearly airfield, built at the beginning of the War. Alison, married to a pilot and newly pregnant, soon makes friends with the locals, particularly with May, who finds herself watching and waiting as the pilots and crew carry out their dangerous missions. Then, on the night when Alison's baby is born, her husband is reported missing and Alison and May find themselves facing a dilemma all too familiar to the wives and sweethearts of those who flew the Spitfires, Hurricanes, and other aircraft to protect their country during this time of war.
