This blue-chip natural history series reveals the rarely-seen magic of the longest river system in the United States and the creatures that are drawn to the Mississippi for survival. The series, and the dramatic twists and turns within each hour, follows the seasons and flows onwards with the river. From winter in the catchment areas in the far north, to the sun-filled Gulf of Mexico, each hour covers a different section of this mighty river. If you only ever thought of the Mississippi as a river of commerce – this will change your view forever. Produced by National Geographic.
