The show format follows Unger as he travels to various locations and interviews local people, visits important historical and cultural sites, and provides commentary from behind the wheel of his car as he drives from location to location. Interspersed with these segments are brief historical synopses by notable US historians. Season 2 premiered in the fall of 2012, with a slightly more reality-oriented format and episodes shortened to half an hour, airing Saturdays on H2, with encore showings on Friday night on the History channel.
