A great, intense movie about war and rape, based on a Vietnam incident of 1966 that was reported in The New Yorker, October 18, 1969, by the late Daniel Lang. He gave an emotionally devastating account of the actions of a squad of five American soldiers who kidnapped a Vietnamese village girl, raped her, and then covered up their crime by killing her. One of the five men refused to take part in the rape, and, despite threats and attempts on his life, forced the Army to bring the other four to trial. He’s the one who suffers from guilt: he can’t forgive himself for his inability to save the girl’s life. Directed by Brian De Palma, the movie is the culmination of his best work.
