Sir Trevor McDonald takes an adventure along the Mississippi River. Starting at the Gulf of Mexico, Sir Trevor's journey leads him to encounter an array of characters and locations. At 2,320 miles long, the Mississippi River, often referred to as 'Ole Miss', represents the heart of America. It's the prism through which the story of America's past and present can be told. Today the Mississippi has turned the United States into one of the greatest food producers in the world. 'Ole Miss' is also responsible for bringing together the different music styles and influences that lead to the birth of rock 'n' roll. Stepping away from the redneck, backwater stereotypes, Sir Trevor will show viewers how the Mississippi is still influencing lives and culture today.
