John Catselas is a television news cameraman. In one of the opening scenes, a group of cameramen and journalists are discussing the ethical responsibilities within their profession: when should filming a gruesome scene end and human responsibility to try to save a life begin? As viewers we are presented with issues such as violence as spectacle, political and social discontent, extreme racism, and class divisions. The film is constantly juggling documentary footage with feature film image. Among his sources, Wexler uses footage from military training camps in Illinois for military troops preparing for planned demonstrations by students and Opposition to the Vietnam War during the 1968 Democratic National Convention later that summer.
