A documentary showcase on the PBS television network features a film this week about the recent history of  Argentina. Juan Mandelbaum uses his painful memories of a lost girlfriend to explore the stubborn pain inflicted from 1976 to 1983 when the nation’s military took control of the government in a film called “Our Disappeared.” The regime, in the name of fighting communist revolutionaries and other threats to internal security, used methods such as abduction, torture, and assassination that earned the period the name “dirty war.”

The website for the film is well done.
