Philippe Charpentier crafts enviable wines in the heart of southern France. His wines grace the tables of the world's most prestigious restaurants.

When Philippe is found unconscious in his vineyard, surrounded by blood, the idyllic future of his winery is threatened. What happened? Wilted vines are discovered in the vineyard. Was Philippe aware of this? And what role does Véronique, his former lover who now works for Cropinova, play?
