The widow Champbaudet believes herself loved by an architect. But the young man actually has views on the neighbor upstairs. Cunning, he multiplies his visits to the widow with the sole aim of getting closer to the beautiful Aglaé. It was without counting on the husband of this one, whose jealousy could well play nasty tricks on the heartthrob of these ladies!
