Chilean students occupy schools and fill the streets in what the film calls the largest protests the country has seen in decades, demanding free education and an end to the privatization of schools and universities. Al Jazeera's Fault Lines traces that policy back to Augusto Pinochet, who built Chile's free-market education system in the final days of his dictatorship, and follows how decades of that arrangement have deepened inequality between rich and poor. Interviews with student leaders and activists lay out why tuition and school fees have become the flashpoint, while the film tracks how the unrest has turned into a political crisis for President Sebastian Pinera. It also places Chile's protests alongside a wider wave of demonstrations happening elsewhere in the world at the same time, asking what connects them. The film stays close to the students themselves, on campuses and in marches, rather than treating the story as a distant policy debate.
