The play was produced by Hillard Elkins, directed by Edwin Sherin, and starred George S. Irving, Gene Rupert, Humbert Allen Estredo, Stephen D. Newman, Philip Sterling and Robert King.
The play is a wry examination of the career and Presidency (up to that pre-Watergate point) of Richard M. Nixon (Irving).
As it starts, two pundits, a William F. Buckley-like Pro (Rupert) and a Gore Vidal-like Con (Estredo) are debating the worthiness of Nixon.
Unable to settle their differences objectively, they magically convene a tribunal of deceased, past Presidents — Dwight D. Eisenhower (Sterling), John F. Kennedy (King) and George Washington (Newman) — to review the Nixon career and pass judgment.
[1] The published version of the play, prepared prior to rehearsals, features only the tribunal of presidents, but not the characters of Pro and Con, who were added later.
