A fortune teller predicts that Dr. Přelouč will marry the third poor girl he meets. Míla, the daughter of factory owner Janota, likes the doctor and, with the help of his housekeeper Amálka, sneaks into his home disguised as a poor shoelace saleswoman. She first prepares for her role by exploring the outskirts, where she meets Vendelín Pleticha, who becomes her guide to the local pubs and her teacher of the vernacular. Dr. Přelouč is enthusiastic about the poor, uneducated girl and tries to teach her the basics of social behavior and standard language. All this until he discovers that Míla has deceived him and that Pleticha is not her father, as she had claimed...
