Les Troubadours, a folk music group that Bruno has long supported, go viral with their new number, "Song for Catalonia," when the Spanish government suddenly bans the song. The songwriter, Joel Martin, is a local enthusiast for the old Occitan language of Périgord and the medieval troubadours, and he sympathizes with the Catalan bid for independence. The success of his song provokes outrage among extreme Spanish nationalists. Then, in a stolen car found on a Périgord back road, police discover a distinctive bullet for a state-of-the-art sniper's rifle that can kill at three kilometers, and they fear that Joel might be the intended target.

The French and Spanish governments agree to mount a joint operation to stop the assailants, and Bruno is the local man on the spot who mobilizes his resources to track them down. While Bruno tries to keep the peace, his friend Florence reaches out for help. Her abusive ex-husband is about to be paroled from prison and she fears he will return to reclaim their children. Will Bruno and Florence be able to prevent this unwanted visit? Despite the pressures, there is always time for Bruno to savor les plaisirs of the Dordogne around the table with friends.
