From NetFlix:

A startling discovery comes to light for retired Argentine criminal investigator Benjamín Espósito (Ricardo Darín) as he pens a biographical novel about the unsolved case of a young newlywed’s brutal rape and murder years ago. Past and present intertwine for Espósito and colleague Irene Menéndez Hastings (Soledad Villamil) in director Juan José Campanella’s Oscar-winning character study in which justice, pain and love collide.

Compare this film with The Official Story (1985). Both deal with the corruption that is Argentina. “The Secret” occurs during the time of Eva Perón and therefore in the 1940’s and 50′. “The Official Story” takes place a few years after the “Dirty War” and there in the 1980’s.

Obsession with justice and an inability to forget the past is the prevailing theme. Corruption during the era of Perón accounts for the difficulty Espósito finds in obtaining justice.

Some dialog is wonderful witty banter. Some dialog shows the ugliness inherent in the Argentinian culture. The acting is wonderful.

On one level this is a story of frustrated love. On another level it is about obsession with justice. On another level it is about official corruption.

At many points I assumed the film had ended. But wait … there’s more! Finally there is a surprise ending that you may or may not expect. Sorry, no spoilers !
