In the spring of 1881. Bass Reeves, the first black Federal Marshall in US history, was called upon by an old friend, Cherokee Tribal Policeman Charlie Next Moon, to help track down a man who had murdered in cold blood two Cherokee women and a white reservation school teacher in the Indian Territories of Oklahoma. Both men were seasoned lawmen, but neither was prepared for what faced them out on the murderer's trail. And even after witnessing the brutality of the killing fields of the Civil War, the horrors they would witness in their pursuit of this crazed killer would haunt them both for the rest of their lives.
