American Josie Anderson and Parisian Arlette LaRue are heroes of the French resistance, stealing so many Nazi secrets that they become known as the Golden Doves, renowned across France and hunted by the Gestapo. Their courage will cost them everything. When they are arrested and taken to the Ravensbrück concentration camp, along with their loved ones, a shadowy Nazi doctor does unspeakable things to Josie's mother, a celebrated Jewish singer who had joined her daughter in Paris when the world seemed bright. And Arlette's son is stolen from her, seemingly never to be seen again.
A decade later the Doves fall headlong into a dangerous dual mission: Josie is working for U.S. Army Intelligence and accepts an assignment to hunt down the infamous doctor, while a mysterious man tells Arlette that he may have found her son. The Golden Doves embark on a quest across Europe and ultimately to French Guiana, discovering a web of terrible secrets, and must put themselves in grave danger to finally secure justice and protect the ones they love.
