Teresa is a beautiful and intelligent young woman, desperately seeking to leave the grinding poverty of the neighborhood where she lives. Despite being beautiful and having support and love from her parents, she lives a miserable and resentful life. After her sister Rosa dies from a heart disease, Teresa vows that she will never be poor again, making plans to escape the life of poverty surrounding her, using her beauty as a way to make it to the top. She is in love with Mariano, a man who lives in the same neighborhood with her and is studying to become a doctor in order to meet Teresa's expectations and fulfill all her dreams. But Teresa is impatient.
While studying at an exclusive school on a scholarship, Teresa meets Paulo, a wealthy young man and very popular among all students. Teresa, seeing him as a way to get rich fast, breaks up with Mariano and uses her beauty to charm Paulo. They go out throughout high school, but, upon discovering she is poor, he immediately breaks up with her.
Paulo and Aida, Teresa's jealous classmate, humiliate Teresa, publicly displaying her poverty and her lies, so Teresa decides to take revenge and swears to never be trampled on again. "Entre ser y no ser, yo soy (if I have to choose between being a nobody or a somebody, I will be a somebody)" becomes Teresa's motto and the motto becomes the basis for the telenovela.
Teresa befriends her teacher Arturo de la Barrera, a respected lawyer who offers to pay for her education. Teresa decides to make Arturo fall in love with her. However, seeing that her friend Aurora is in love with Mariano, she's filled with jealousy and decides to get back together with him.
