El Secreto de sus Ojos
This is the film that beat A Prophet to the 2010 Best Foreign Language Film Oscar and only the second Argentine film to win that category. It was a result that left a lot of critics surprised due to the strength of the competition.
Buenos Aires, retired legal investigator Benjamin Esposito (Ricardo Darin) is writing a book about a troubling case from 20 years previous in 1974, the investigation of a brutal murder-rape of a young and beautiful school teacher named Liliana Coloto. Esposito interrogates his memory to order events which involved his superior, Irene Menendez Hastings (Soledad Villamil) and his drunken subordinate Pablo Sandoval (Guillermo Francella) battling institutional problems to establish the truth. As he writes the book he finds himself troubled even more the events and allows Hastings to read it to help solve the case and lay down memories and feelings.
