We follow
in almost
real time a handful of individuals forced to make split - second decisions after this incomprehensible event that would
change their lives and forever alter our
world's landscape: the young doctors and nurses at Parkland Hospital, the chief of the Dallas Secret Service, the unwitting cameraman who
captured what has become the most watched and examined film
in history, the FBI Agents who had gunman Lee Harvey Oswald within their grasp and Vice President Lyndon Johnson who had to take control of a country
in a moment's notice.
