When John Stafford, a young man from a wealthy Philadelphia family, graduates from college in the 1860s, he ventures to the lawless Northwest to satisfy his basic urge to put himself to the test in meeting the challenges of a trying environment. Adventure is what he seeks, and adventure is what he gets. Stafford experiences many turbulent twists and turns in his life. He marries, Little Dove, a beautiful Indian woman of Hidatsa descent. He is accepted into her tribe following his ingenious strategy to defeat his wife's wrathful Blackfeet suitor. And Stafford accepts a request by President Abraham Lincoln to form a highly proficient clandestine fighting force to help the Indians defend themselves against the widespread tyranny. His skilled force consists of several relatives and close friends-black as well as white, male and female, along with a number of Native Americans. Their exploits involve confrontations with river pirates, whisky peddlers, a tragic massacre by unauthorized military action an Indian reprisal, and a marauding gang of cutthroats.
