Amidst war's uncertainty, what becomes of love?
In war-torn London, American Kate Isaacs grieves her husband, awaits their child's birth, and welcomes her best friend, Addie. But after her miscarriage, another meeting with mysterious Monsieur le Blanc launches her into Britain's Secret Operations Executive, the SOE. In late 1943, Kate parachutes into southern France to aid the Resistance.
Domingo, a grieving Basque mountain guide turned saboteur, meets her parachute drop, tends to her injured ankle, and carries her to safety. Reunited a few months later, they discover the injured Monsieur le Blanc who, with his dying breath, reveals a secret that changes Kate's life.
In the shadow of the Waffen SS, Domingo's younger brother Gabirel is missing. While Domingo seeks Gabirel, Domingo's parish priest, Père Gaspard, creates a new identity for Kate.
As Kate and Domingo subject their mutual attraction to the cause of freedom, can mere human will and moral courage change the war's tide and forge a future for them?
