Chris (Charlie Sheen) is an infantryman whose loyalty is tested by two superior officers: Sergeant Elias (Willem Dafoe), a former hippie humanist who really cares about his men, and Sergeant Barnes (Tom Berenger), a moody, macho soldier who may have gone over to the dark side. The personalities of the two sergeants correspond to their combat drugs of choice--pot for Elias and booze for Barnes. Stone has become known for his sledgehammer visual style, but in this film it seems perfectly appropriate. His violent and disorienting images have a terrifying immediacy, a you-are-there quality that gives you a sense of how things may have felt to an infantryman in the jungles of Vietnam.
