The first part of the film concentrates on the personal lives of the air crew, including their problems and relationships. For family reasons, one of the pilots has had to give up a promising career for a much less ambitious one. Despite this, his wife senses that he is not happy, which makes her a conflicted and angry spouse. Although both the parents love their son, it is not enough to prevent them from divorcing. Subsequently, the pilot resumes his career piloting the large passenger planes he had been hankering after. One of his pilot colleagues does not believe in family at all — his flat is full of impressive self-constructed light effects and son et lumière (show) equipment that he uses to impress the parade of women he has one-night stands with.
