JFK

New Orleans District Attorney Jim Garrison (Kevin Costner) is convinced that there are some big flaws in the investigation of Oswald (Gary Oldman), and he sets out to recreate the events leading up to the assassination. Along the way, he stumbles across evidence that a great many people had reason to want to see the president killed, and he is convinced that some of them worked in concert to frame Oswald as the killer.

Among the suspects are Lyndon Baines Johnson (the next president), the CIA, J. Edgar Hoover, and the Mafia. Over the course of gathering what he believes to be evidence of a conspiracy, Garrison unveils some of the grittier aspects of New Orleans society, focusing on the shady activities of local businessman Clay Shaw (Tommy Lee Jones). Garrison's in­vestigations culminate in his conducting a show trial that he knows he will lose and which he is sure will ruin his career in order to get his evidence into the public record where it can't be buried again.
