Barney Morgan, slight for a boy in his early teens, finds that he has what it takes to be a pioneer in this story of gold prospecting in Montana. When news reaches the boy that his father has perished while on a prospecting trip, he is convinced this is untrue, and sets out across the Montana territory to find him. En route he meets a medicine man and becomes involved in his troupe. Exploited and virtually imprisoned by the charlatan, Barney, with the help of Sampson, a blind strong man, finally escapes from the medicine wagon and together they reach Butte where Barney's father welcomes them and exposes the fraudulent medicine show. A fast paced story with a vivid, detailed, and unusual perspective of the Montana territory, prior to the advent of the railroad.
