Recounting the chaotic events that occurred in Dallas Texas on November 22 1963 Parkland weaves together the perspectives of a handful of ordinary individuals suddenly thrust into extraordinary circumstances: the young doctors and nurses at Parkland Hospital, Dallas' chief of the Secret Service an unwitting cameraman who captured what became the most watched and examined film in history, the FBI agents who nearly had the gunman within their grasp, the brother of Lee Harvey Oswald, left to deal with his shattered family and JFK's security team witnesses to both the president's death and Vice President Lyndon Johnson's rise to power over a nation whose innocence was forever altered.
