Taking place in 1963 in the days following the assassination of President John F. Kennedy, Jackie chronicles the experiences of First Lady Jacqueline Bouvier Kennedy (Natalie Portman) as she copes with tumultuous grief, change and the scrutiny of both America and the international community in the immediate aftermath of her husband's death. Her relationships with her own children, members of the Kennedy family, such as JFK's brother Robert, and Kennedy's successor, President Lyndon Johnson, are explored in the wake of the tragedy.
