The investigation is reopened in 1966 after Garrison reads the Warren Report and notices what he believes to be multiple inaccuracies. Garrison and his staff interrogate several witnesses to the Kennedy assassination, and others involved with Oswald, Ruby, and Ferrie. One such witness is Willie O'Keefe, a male prostitute serving five years in prison for soliciting, who reveals he witnessed Ferrie discussing a "coup d'état". As well as briefly meeting Oswald, O'Keefe was romantically involved with a man called "Clay Bertrand".
