It was a feast day in Piolenc, a small town in the south of France, in the summer of 1912. The Barloti family had come from Corsica for a wedding. It was a day of drama too, for little Rosa, 7 years old, was to disappear in an shadowy mystery, leaving only her pretty pink dress to be found a few meters from the house, stained with blood. In this Corsican family, there is an extra chromosome, the V of revenge. However long it takes, honour will be upheld.

Piolenc, September 2018. Ange Barloti, great-grandcousin who manages the family estate, learns that the body of a child has been found when watching television. It is indeed Rosa. Romilda and Laura are friends with opposing personalities. Laura is all modernity. Romilda, on the other hand, is harbouring wounds from her love life when a flood leads her to find a treasure – letters written by a soldier named Felix to his fiancée during the First World War. She then begins a correspondence that, like Ariadne’s thread, leads to the path of truth.
