Mazurkiewicz, a lawyer from Radom, arrives in Warsaw to ask for Sabina's hand in marriage. Sabina is secretly in love with young Władzio Mącki, who, being preoccupied with the beautiful cabaret actress Kamilla, pays no attention to the young girl. At the request of the Mąckis, Mazurkiewicz goes behind the scenes to seduce her, but he himself succumbs to her charms and gets involved in an incredible scandal. Sabina follows Mazurkiewicz to the theater to warn her beloved, and when she meets Kamilla, at her urging, she changes into her dresses and imitates her mannerisms, winning Władzio's heart. Mazurkiewicz invites Kamilla to his hotel for dinner, where all the members of the Mącki family arrive one after another. Amidst spasms, arguments, and laughter, the situation is resolved to everyone's satisfaction.
