In 1804, Leslie Edwards, a foppish aristocrat, and the loud, low-brow Bartholomew Hunt are competing against the renowned Lewis & Clark to be the first to chart and make it across the United States to the Pacific Ocean. In the beginning of the film, Edwards has high hopes to head the first expedition to make it across the U.S., but while he has ambition and funding, he has grown up sheltered and knows little of the wilderness he seeks to cross. To aid in his journey, he hires the services of a supposedly knowledgeable wilderness-man and tracker, Hunt, who, once they get underway, turns out to be less than advertised.
