Professor Charpentier’s wife Irene has no fear of flying. While her entomologist husband is busy studying the love life of the stag beetle, the neglected housewife takes an aerial spin with Baron Felix. Less obvious, but no less compelling, are the sparks between Irene and the sculptor Preben. When he starts to believe the attractive young woman is guilty of adultery with the flying daredevil, it could have fatal consequences. “I don't like plays with a tragic end. In this respect I agree with the cinema audience”, Professor Charpentier proclaims after a night out at the ballet. Mauritz Stiller seemingly agreed and his exemplary adaptation of a Hungarian light comedy provided the basic model for the elegant, erotic drawing room comedies later perfected by directors like Ernst Lubitsch or George Cukor.
