London - Summer 1943. To honor her husband’s sacrifice—and in hopes of learning more about her father, a World War I vet—widow Kate Isaacs joins the Special Operations Executive and parachutes into Nazi-occupied France to work with the Resistance. Domingo, a Resistance saboteur, meets her drop, tends to her sprained ankle, and carries Kate to her first assignment. During a clandestine mission Kate finds herself attracted to Domingo, but as Allied forces push across France and the Waffen SS closes in, the pair must put aside their feelings for the good of the Underground Resistance. Will moral courage and righteous faith triumph over oppression? Or will Kate and Domingo lose everything, including their growing affection for one another?
