What would you risk to get what you want? June 1940. As Paris, the City of Light, approaches its darkest hour, a young woman treads the line between survival and collaboration. Londoner Cora Masson has reinvented herself as Coralie de Lirac, using a false claim to aristocratic birth to launch herself as a fashionable milliner. When the Germans invade, the influence of a high-ranking lover saves her business. But in striking this pact, she retains her position as designer to a style-hungry elite, but becomes hostage to a life of plenty in a city that is starving to death. As one by one her friends 'disappear' to unknown fates, will Coralie be brave enough to abandon her passion and join the Parisian Résistance?
