How far will you go to protect your family? Jorge is a peaceful hard-working man who seeks a simple, quiet life for himself and his family. One day, he is mugged and humiliated by a gang of thugs led by Kalule, a delinquent from his neighborhood. This event infuriates his son as much for Jorge’s meek acceptance as for the act itself. The son, looking for retribution, ends up getting himself shot. Kalule is sent to jail and when he gets out 18 months later, begins a campaign of terror against Jorge and his family. The authorities do nothing, so Jorge decides to take matters into his own hands.

Santiago, capital of Chile during the Marxist government of elected, highly controversial president Salvador Allende. Father McEnroe supports his leftist views by introducing a program at the prestigious “collegio” (Catholic prep school) St. Patrick to allow free admission of some proletarian kids. One of them is Pedro Machuca, slum-raised son of the cleaning lady in Gonzalo Infante’s liberal-bourgeois home. Yet the new classmates become buddies, paradoxically protesting together as Gonzalo gets adopted by Pedro’s slum family and gang. But the adults spoil that too, not in the least when general Pinochet’s coup ousts Allende, and supporters such as McEnroe.
