For Maria Isabel Salazar Lopez, the hardest thing about being the new girl in school is that the teacher doesn't call her by her real name. "We already have two Marias in this class," says her teacher.

Can she find a way to make her teacher see that if she loses her name, she's lost the most important part of herself?
