A farm near Laguiole, in the Aubrac countryside. Luc Olié, forty, is found murdered with a bullet in his chest. Elisabeth Richard, the deputy public prosecutor, and Paul Jansac, the police chief, are in charge of the investigation, which turns up more and more culprits. Jealousies, old family grudges, a food-labeling scam - There's no shortage of leads, and Elisabeth Richard is a single-minded investigator, sparing neither the town nor Captain Jansac.
