In the United States, it feels like all highways lead to places with the same name more than 200 towns and counties called Liberty. In this historic election year, a new documentary Liberty USA explores the messy business of America's most celebrated value in a number of ways and places. At the heart of the film is a revealing and rollicking road trip through America, with pit stops in six towns named "Liberty". In each place, we find a rich vein of characters grappling with issues that lie at the centre of how Americans define their freedoms in an election year and in the 21st century. And as we see in these towns, liberty is always in jeopardy and conflict.
