We accompany singer Anne Etchegoyen on the journey undertaken every winter between 1870 and 1940 by hundreds of women from Navarre and Aragon—known as the "swallows" because of their migratory resemblance to birds—across the Pyrenees to the French Basque Country to work in the espadrille industry and then return home in the spring to help the local economy, start their own families, and begin a new life. A journey through time, geography, and historical and personal circumstances, through archives, documents, photographs, and interviews.
