In pre-WWI France, 17-year-old Suzanne Malherbe is entranced by the brilliant but troubled Lucie Schwob. They embark on a clandestine love affair, but in an astonishing twist of fate the mother of one marries the father of the other. As 'sisters' they are finally free of suspicion, and move to Paris at a moment when art, literature, and politics blend in an explosive cocktail. Reinventing themselves as Claude Cahun and Marcel Moore, they produce provocative photographs that still seem avant-garde today. In the 1930s, with the rise of anti-Semitism and fascism, they leave Paris for Jersey, and create a campaign of propaganda against Hitler's occupying forces that will put their lives in jeopardy.
