A young artist, Hippolyte Schinner, has an accident in his studio and is helped by a mother and daughter who live in a neighboring apartment. The daughter, Adélaïde, is beautiful and the artist falls in love. But, every evening the mother seems to win a large amount at cards. Has Hippolyte fallen into a gambling den? Then his purse goes missing. Meanwhile Hippolyte's mother, having made inquiries about her son's condition and having learned of the whole affair, informs the Comte de Kergarouet of the malicious rumors surrounding the two women. Outraged, he explains to Madame Schinner that he loses intentionally at cards to Madame de Rouville because the Baronne's pride has left him none but these ingenious means of assisting her and her daughter in their poverty. The Comte de Kergarouet and Madame Schinner go round to Madame de Rouville's, and arrive just in time to pronounce a benediction on the young lovers' engagement.
