A small city in western France, the early 1900s. Suzanne, a shy 17-year-old with a rare talent for drawing, is entranced by brilliant but troubled Lucie, the daughter of a Jewish newspaper magnate, and the two young women embark on a clandestine love affair. Suffocated by provincial convention and the restrictions of their gender, Lucie and Suzanne reinvent themselves as Claude Cahun and Marcel Moore and move to Paris. Before too long, they are mixing in the most glamorous social circles, meeting everyone from Ernest Hemingway and Salvador Dalí to Andre Breton. Moreover, they are producing surrealist photographs of great power and strangeness. As World War Two looms, they leave Paris for Jersey, and it is here that they confront their destiny, dreaming up a campaign of propaganda against Hitler’s occupying forces that places them both in great danger.
