A powerfully written and directed film, with brilliant dramatic performances by Jack Lemmon and Sissy Spacek. Costa-Gavras retells the story of a conservative American businessman and his radical daughter-in-law as they seek out information about her missing husband, his only son. Their relationship develops from an antagonistic, mutually disrespectful and distant one, to a relationship and of profound respect with a deep bond between them. The details of her husband's --his son's-- arbitrary arrest, torture and summary execution, along with the similar treatment of thousands of others, are slowly revelaed and unraveled. The U.S. complicity in the murderous Chilean right wing military coup d'etat of the early 1970's is also revealed. A powerful story and brilliant film.
