Commissioner Moreau wins a week-long stay in Corsica in a raffle held by the Paris police. Relaxed, he admires the beauty of the island. However, on the second day of his vacation, he encounters the darker side of Corsica, the harsh reality. A motorcyclist opens fire on a driver stuck in traffic on the Cours Napoléon, the grand avenue of Ajaccio. The driver manages to return fire, but both are fatally hit. After his week-long vacation, Moreau is unexpectedly transferred from Paris to Corsica. There, he is tasked with uncovering the mystery of where a portion of the three billion euros that Corsica receives from Paris each year disappears, while also investigating the constant attacks and bombings that plague the island. Essentially, a hopeless endeavor.
