Brought up in privilege, Jacqueline Bouvier marries men of wealth and power.

After separating from Jack Kennedy, Jackie gives her in-laws an ultimatum as the price for reconciliation; life in the White House; JFK's relationship with Marilyn Monroe; Jackie meets Aristotle Onassis.

After the assassination, Jackie moves to New York; she weds Onassis, but problems with Christina and, eventually, Ari cause the union to deteriorate.
