It was the dawn of a nation — a time before the American West became known as the frontier, and little was known about what lay within.

Two captains, courageous in spirit and unyielding in their dedication to their mission, led 31 people, including one woman and her infant son, to the Pacific Ocean and back. Now, 200 years after the launch of the expedition, this breathtaking drama is captured for audiences in the newest large-format release from National Geographic. Audiences will experience the danger and beauty of the unknown West as it unfolded before the eyes of Lewis and Clark. The movie is narrated by Jeff Bridges.
