Senator Charles Carroll (William "Bill" Boyce), an independent senator, is holding a luncheon atop the Seattle Space Needle. Joe Frady (Warren Beatty), an alcoholic journalist, tries to gain entry to the luncheon, but is turned away. At the restaurant atop the Space Needle, Senator Carroll is holding a press conference when he is suddenly shot to death by an unseen assassin. Everyone looks around and sees a waiter holding a gun, and he is jumped by security guards. However, a second waiter (Bill McKinney), who also has a gun (and the real or second shooter) leaves unnoticed. The first waiter replies that he didn't do it, and he is chased over the roof of the building by guards, where he accidentally slips and falls off the roof to his death. The real assassin chuckles as he leaves the scene and reports to an unseen contact that the job is finished. Four months later, a commission holds a special public gathering and they conclude that the waiter, named Thomas Richard Lindern (Chuck Waters), acted alone and that there is no greater conspiracy to the assassination of Senator Carroll.Three years later. Joe Frady, writing for a Portland, Oregon newspaper, sets himself up to get arrested to get a story on a major drug bust. Frady is bailed out of jail by his boss and editor Bill Rintels (Hume Cronyn) who always complains that Frady is trying to create news rather than reporting it. Shortly thereafter, Frady is visited by Lee Carter (Paula Prentiss), a Seattle newscaster and his former girlfriend, who tells them that she fears for her life. Lee tells Frady that someone is trying to kill her and that six other reporters at the luncheon have all died mysteriously during the past two years. Frady shrugs her off by telling her that she's just being paranoid. But a few days later, Lee is found dead in her apartment. Frady investigates and the coroner tells him that she apparently killed herself with an overdose of sleeping pills, but Frady knows different.Frady tells Rintels that there is a story...
