Biography
Mia isn't the most popular girl at school in Mexico, but she is also an expert in diving thanks to her father. In that school she is a victim of bullying and not even her step-sister, Sasha, wants to be friendly with her at school. She joins Sasha and their two friends in their quest to explore in a submerged dive a sunken Mayan city, where her father is working, only to be trapped by a group of white sharks that are swimming in it.

After that they have to fight to save themselves. In this struggle, in which they bond, their friends, her father and two other workers who were working there at that moment die. Still, they are both able to save themselves, in which she, in a heroic action, nearly sacrifices her life to save her stepsister using for that all of her skills in diving, an event that even intimidates her bullies.

By the end of the film, Mia is the remaining survivor along with Sasha and, because of the events, they become real close while their wounds are being treated.
