The narrative centers on an orderly Paris household dominated by a controlling sister and her obedient brother, whose ward, a spirited young woman married to a rakish captain, brings gaiety and recklessness. When the household parrot escapes and the couple's extravagant tastes surface, a chain of social outings, flirtations, debts, and incidents at music halls and dinners produces misunderstandings, family anxieties, and minor scandals. Through comic episodes, revelations about spending, romance, and loyalty play out among servants and relatives, culminating in reconciliations and a restoration of domestic order tempered by newly exposed truths.
