Diane Keaton is romanced by politician Ed Harris, and comes under the spotlight when Ed runs for the Presidency.
She makes all sort of stands on serious issues and is deemed a loose cannon by Ed's aides, but the real problem arises when tabloid sleaze Russ Tamblyn unearths an underground film Diane made in 1967 (a brilliant pastiche) in which she has steaming sex with a guy dressed as Nixon while wrapped in the Stars And Stripes. You'll never believe the ending, but it's a worthy nonetheless.
