The aftermath of the shooting deaths of four college students at Kent State on May 4, 1970 has been called the most divisive moment in American history since the Civil War. This compelling documentary returns to that turbulent spring 45 years ago to take a new perspective on the incident and what followed by exploring how three very different worlds – U.S. college campuses, the jungles of Cambodia and the Nixon White House – collided during that month in 1970.
