A small city in western France, the early twentieth century. Suzanne Malherbe, a shy 17-year-old with a rare talent for drawing, is entranced by the brilliant but troubled Lucie Schwob, the daughter of a Jewish newspaper magnate, and the two young women embark on a clandestine love affair.
Stifled by provincial convention and a society that is overtly patriarchal, they reinvent themselves as Claude Cahun and Marcel Moore and move to Paris, where they are swept up in the most glamorous social circles, meeting everyone from Hemingway and Dali to Andre Breton. While there, they produce a series of provocative photographs that still seem avant-garde today. As World War Two looms, they leave for Jersey, and it is on this idyllic island that they confront their destiny, dreaming up a campaign of propaganda against Hitler’s occupying forces that will put their very lives in jeopardy.
