Banker Jules Taffard, a true financier, is a shrewd money-handler. Imprisoned for an alleged swindle, his trial seems to be upsetting those in the government, who may not be so far removed from Taffard's affairs (Affaire Alexandre Stavisky). He escapes from La Santé prison without any difficulty, and the authorities don't seem to be doing anything to find him... Under the false name of Gédéon, he becomes a modest handyman in a corset shop run by Madame Génissier, whose morality is as pious as it is legendary. Her son, Hector Génissier, is a foolish young man with no ambition, much to the regret of his young wife, Fernande Génissier. But it won't be long before Gédéon shows his skills in expanding the modest family business. How far can Gédéon's ascent go before Taffard's voice resounds through Gédon?
