Fatherless since childhood and bullied by her own relatives, a determined girl is driven out of her village with nowhere to go. But no hardship can crush her love for math. Lifted up by two devoted teachers, she rises from the bottom to stand at the peak of a global competition. Now the family who tormented her and the neighbors who cast her out can only watch in regret as she takes the world stage.
