This informative documentary was nominated for an Academy Award in 1986 and is an important resource for one particular dark page in Argentina's modern history. Starting in the '70s, the Argentine government was responsible for the "disappearance" of 30,000 dissidents. One of the first organizations to form against this slaughter was a group of mothers who had all shared in the agony of going from one bureaucratic pillar to another bureaucratic post, trying to locate their sons or daughters. Their politically active children had simply "disappeared." No one paid attention to the mothers, but their numbers rapidly jumped to 300, and when they first gathered in the Plaza de Mayo the police tried to disband them. Governmental persecution increased, but the Association of the Madres del Plaza de Mayo is still active today. They tell their stories here in this documentary -- and have several sites on the Internet that bring their currently international activities up to date.
