At the edge of the city and the margins of society, a school and its students are fighting back.
Papakura High School has a falling roll, and as far as results go, it's among the worst schools in the country.

Some of the students are stars, dedicated to building a future for themselves and inspiring others.
A charismatic new headmaster has big plans for turning things around.
