Champagne, 1940: Inès has just married Michel, the owner of storied champagne house Maison Chauveau, when the Germans invade. As the danger mounts, Michel turns his back on his marriage to begin hiding munitions for the Résistance. Inès fears they’ll be exposed, but for Céline, half-Jewish wife of Chauveau’s chef de cave, the risk is even greater --- rumors abound of Jews being shipped east to an unspeakable fate. When Céline recklessly follows her heart in one desperate bid for happiness, and Inès makes a dangerous mistake with a Nazi collaborator, they risk the lives of those they love --- and the champagne house that ties them together.
