Susana is an unappreciated, naive and somewhat clumsy orphan who has lived since she was a child at doña Engracia's house, because her mother died a few days after she was born. In this house, which also houses three nephews of doña Engracia without a penny to one's name, Susana is the maid of all. Economic necessities lead Engracia to rent a room. Felipe, a handsome man with a bad reputation, will reply to the ad.
