Welcome to San Antonio, the big little city, where everyone has an opinion about everybody...especially if you're Mexican. While hosting the ultimate Cinco de Mayo bash, Mayra is taken aback by Luz's strong judgements of her, and Penny proclaims she doesn't care who judges her. Meanwhile, Mayra's close amigas (friends) Lorena and Karla, try to get to know Luz better, while Mayra offers Anayancy help with planning a charity event.
