On September 11, 1973, President Salvador Allende's democratically elected Chilean government was overthrown in a bloody coup by General Augusto Pinochet's army.

Patricio Guzmán and five colleagues had been filming the political developments in Chile throughout the nine months leading up to that day. The bombing of the Presidential Palace, in which Allende died, would now become the ending for Guzmán's seminal documentary The Battle of Chile (1975-76), an epic chronicle of that country's open and peaceful socialist revolution, and of the violent counter-revolution against it.
