Bruno on special assignment: a group of old friends who know each other from Silicon Valley meet up every year for a week's holiday, this time at the beautiful, luxurious Château de Rouffillac. But beforehand, one of them, Brice Kerquelin, is the victim of a mysterious "accident" and Bruno is seconded to protect the small group. But it's not just his ingenuity but also his culinary skills that are in demand: in the seclusion of the château, he arms himself against attacks and takes care of their physical well-being with tarragon chicken and tarte tatin.
