Léo, a prostitute yearning for love, kisses his clients, contrary to his colleagues. Passionate and bright, he makes his way through a dodgy, dangerous world. The punches received often hurt. The loved one runs away from feelings. But ties of brotherhood ease the pain. Léo remains open to others and to love. Driven by the feverish acting and the animal beauty of Félix Maritaud - the revelation of Robin Campillo's "120 Beats Per Minute" - this first feature film, full of mastery and intensity is, despite its darkness, a dazzling success.
