Bernard, a successful architect living in Paris, thinks he can easily cope with his three air-hostess fiancées. It is all a question of timetables and a reliable, long-suffering housekeeper who reluctantly has the role of romantic air-traffic controller. When old school friend Robert arrives, Bernard relishes the chance to show his wide-eyed visitor his first-class operation at work. Unfortunately, schedules change, flights are delayed and a new turbo-charged Boeing aircraft is introduced: chaos ensues in this hysterical whirl of mayhem and matchmaking.
