1924, near Paris. Josef has settled down with Adèle... but still dreams of flying. Yet even with his new pilot's license, he lacks the experience that will make the airlines take him seriously. Bored and frustrated, he accepts a job with a flying circus, standing in for an injured pilot. Though extremely dangerous, and despite Adèle's objections, he sees this as a chance to rack up some flying time—and as a first step toward becoming a professional pilot. His goal is to join the new airmail service run by Latécoère, later to become famous as Aéropostale. Its owner plans to extend the service from Toulouse to Dakar—a project fraught with danger... and excitement!
