In Part 2, the expedition begins! Join the Corps of Discovery as they eat their way across 8,000 miles, shoot at grizzly bears, hold intertribal talent shows, and search for the Pacific—while surviving on dried meat and questionable water. We follow them from Missouri to the ocean and back, plus take a look at what happened after the journey, including mysterious deaths, political drama, and what the founding fathers never told you about unpaid expense reports.
