On May 4, 1970, Kent State in Ohio was one of many American college campuses roiled with student protest over the U.S. invasion of Cambodia. On that day, National Guardsmen opened fire on the demonstrators─killing four, wounding nine more─and precipitated the most divisive moment in national history since the Civil War. That unforgettable day─and its immediate aftermath─is illuminated in this remarkable effort. 60 min. Widescreen; Soundtrack: English Dolby Digital stereo; Subtitles: English (SDH).
