In 1973, Chile undergoes a coup d'etat. 30 years later, it appears that it was - alongside with all the coups in the southern cone - organised by the CIA in order to stop the possibility of having a communist block on its south.

With confidential and unpublished documentation, the film shows the background and behind-the-scenes of the coup in Chile that took place on September 11, 1973 - and General Pinochet's dictatorship, which lasted 17 years.
