Michael Portillo continues his journey from the northern state of Minnesota to the Deep South. Michael discovers the story of Hiawatha and his lover Minnehaha, an epic poem featuring American Indian characters. He then meets a Dakota Sioux expert on Native American culture to learn about a dark chapter in United States history and how it is marked today. Michael has to put his diplomatic skills to the test at a Swedish-American lunch, where the centrepiece of the menu is reconstituted dried cod. And there is a taste of the golden age of luxury rail travel as Michael bounces on a bed in a beautifully restored Pullman carriage.
