Jean Poiret stars as Bernard, a young, up-and-coming publisher who has inexplicably fallen in love with Sophie (Dany Saval) a woman working with a 25-watt bulb, when it is turned on at all. Sophie is as well-grounded as daisy fluff and just as serious, yet Bernard goes after her with all the determination of a man blinded by love. After a wild and crazy courtship, the couple marry, but Sophie's personality does not change and she gets him into trouble -- to the point where he almost loses his job.
