The House of the Seven Maidens(1942)

Original title: La Maison des sept jeunes filles

The director of a private institution is the father of seven charming young girls. He has money worries. A rich bachelor, still young, a few years ago advanced him a large sum of money. He makes frequent visits to his debtor; the poor father, as mediocre a psychologist as he is a poor businessman, hammers himself in his head, not guessing that the visitor is reluctant to make his choice between the seven sisters.
