Late in 2006, President Jimmy Carter tours the U.S. promoting his provocative “Palestine: Peace Not Apartheid.” Demme’s camera follows Carter from city to city, home to Plains (population 635), visiting a Habitat for Humanity site in New Orleans, and talking on radio and TV with Teri Gross, Charlie Rose, Diane Rehm, Jay Leno, Larry King, Wolf Blitzer, Tavis Smiley, and Al Jazeera and Israeli pundits, discussing Palestine’s plight and the policies of Israel. Critics speak as well. Between events, Carter talks about Camp David, recent travels, being married, speaking Spanish, and wisdom he learned from Rachel Clark, his nanny. A montage of speeches, awards, and travels ends the film.
