Not One Less

In a remote Chinese mountain village, a teacher is forced to hire a 13-year-old girl to be the class substitute for a month. She is left with 30 sticks of chalk and a promise of an extra 10 yuan if not one student is missing when the teacher comes back. Shortly thereafter, one of the students is forced by poverty to head off to the city. The 13-year-old begins her quest to retrieve the boy, enlisting the help of the remaining students. Through her determination to keep the class together, she not only becomes the salvation of the lost boy but of the whole village school as well.
