1942. Seven-year-old Martine hides in an armoire when the Nazis come to take her father away. Pinned to her dress is a note with her aunt’s address in Paris, and in her arms, a bottle of wine she has been instructed to look after if something happened to her papa. But when Martine arrives in the city, her aunt is nowhere to be found. 1990. Charlotte, a commercial airline pilot, attends an auction with her boyfriend Henri at the oldest auction house in Paris. Successfully bidding on a box of wine saved from the German occupation during the Second World War, Henri gives Charlotte a seemingly inferior bottle he finds inside the box. Cleaning the label, Charlotte makes a shocking discovery that sends her on a quest to find the origins of this unusual --- and very valuable --- bottle of wine, a quest that will take her back 50 years into the past.
