In 1876 Captain Grant Marsh was piloting the riverboat "Far West" up the Bighorn River, to bring Colonel George Armstrong Custer supplies and ammunition. But when he heard of the massacre that occurred at the Little Bighorn, his mission became one of rescue. In order to take on wounded soldiers as passengers, Marsh had to bury $375,000 in gold bars that he was carrying for miners somewhere along the shorelines of the Bighorn River. A friend of Clint Adams' decides to search for that treasure and asks for his help. Of course, there are others searching for it as well, and Clint has to keep himself and his friend alive long enough to hopefully find the gold.
