Historically inaccurate.  Three men went to visit Mr. Nixon prior to his resignation - "Senate Minority Leader Hugh Scott, Senator Barry Goldwater, and House Minority Leader John Jacob Rhodes met with Nixon soon after. Rhodes told Nixon that he faced certain impeachment in the House. Scott and Goldwater told the president that he had, at most, only 15 votes in his favor in the Senate."  Years later Mr. Goldwater was asked if the subject of a pardon was discussed and he said no.
