Margarita (Silvia Aguilar) is a "kept" woman from the countryside, living in Madrid on the money given to her by her sugar-daddy, who earns a little money on the side by performing in a club alongside transvestites. Her brother comes to town to try and get her to stop embarrassing the family and return to their home (and the straight-and-narrow). Instead of reforming, she seduces him into sleeping with her. Similar attempts to induce her to "reform" meet with failure.
