The screenplay was written by prolific Hungarian screenwriter Károly Nóti AKA Karl Noti,[3] based on a stage play by István Zágon.
When she engages a butler, Hyppolit (Gyula Csortos) - who was an educated man, and who has served in the household of a late count for 27 years and traveled around the world with the late Count - their whole life is turned upside down: Schneider has to shave off his mustache, wear a dinner suit for dinner and eat French food instead of his beloved onions and roasted goose, while his wife is bullied by the butler into engaging in gymnastics and a rather meagre diet.
In the meantime, the Schneiders' spirited daughter, Terka (Éva Fenyvessy), falls for their good-looking manager, the former driver István Benedek (Pál Jávor), who keeps secret that he is in fact an engineer with a college diploma.
Things begin to turn upside down, when Schneider follows Hyppolit's suggestions to start dating Mimi (Mici Erdélyi), a singer and dancer at a sleazy night club.
When he fails to show up at a date with her, the girl enters the Schneiders' villa, where a dinner party with important guests - including Makáts's uncle - is taking place, and causes a scandal.
