Hungarian dancer, Tongolele, singers Maria Victoria ("the little ranch girl from the South") and Lola Beltran (who sings romantic music) and comedian Tilín, fail in their acts and have to go back to the city. They write to Prudencia, who has an Actors Boardinghouse with her granddaughter Sonia, telling her they’ve reached success. When they get back to the boardinghouse, Sonia urges them to help her with a mortgage problem. Sonia’s boyfriend, Rafael, has an idea, to pass the artists as a Social Regeneration Committee to aristocrat, Gustavo, and they invite him to the independence day party at the boardinghouse. Pedro Vargas arrives to the party with mariachi and has the brilliant idea to make Victoria and Lola sing eachother’s songs. Everyone goes to the Rincon Tapatio, where Rafael sings to Sonia’s surprise. Then a huge fight take place. The next day, they make Gustavo think he married Victoria: that way they use his uncle’s money to make a production show with the boardinghouse’s artists. Victoria’s boyfriend, Luis arrives from La Havana to conduct the orchestra. She makes Luis think Gustavo is her uncle, and tells Gustavo that Luis is her cousin. After he makes up with Sonia, Rafael sings in a production number. Gustavo finds out he isn’t really married to Victoria, but its his uncle Porfirio, who tries to ruin the premiere of the show, with the help of a Morality League. The audience think everything is part of the show. Prudencia discovers that Porfirio was his long lost boyfriend. Lola and Tongolele slap Pedro Vargas, who had been fooling around with both.
