Leticia Padilla Solís, "Leti", is an intelligent but unattractive girl, rather ugly. She graduated with honors in economics, speaks several languages, is fluent in computers, and is a financial genius. Only, because of his physique, she can't find work. Desperate to find a job, "Lety" decides to accept being hired below her level and takes a job as a secretary at Conceptos, a famous video production company, where ugliness is taboo. The production company "Conceptos" was founded by two good friends: Don Humberto Mendiola, and Julián Villaroel. Unfortunately, shortly after, the Villaroels die in an accident and Don Humberto and his wife Teresita take care of the Villaroels' orphaned children: Ariel, Marcia and Ana Leticia and the successful company.
