Clermont-Ferrand, central France. After meeting Isadora, a middle-aged sex worker, Médéric falls in love with her despite the fact that she is already married. When a terrorist incident occurs in the city center, a young man named Selim, who is homeless, seeks refuge in Médéric's building. This causes a wave of paranoia to spread throughout the neighborhood. Because Mederic feels sorry for Selim and is head over heels in love with Isadora, his life has suddenly become a complete mess.
