Mona Gray (played by Jessica Alba) has only one passion in her life, numbers. Everything else for Mona has been sacrificed in the hopes that her father will get better. As she grew into a woman, Mona becomes a isolated woman in a world that thinks of her as odd and weird. After Mona’s mother kicks her out, she gets Mona a job at the elementary school as the new math teacher. Terrified at first, Mona is faced with students that will test her ability to be able to handle these children without going further into herself. As she shows her new students her love for numbers, Mona is able to make a connection with one girl who is more similar to Mona that this little girl could almost be a mirror image of Mona.
