A lesser known part of the American Revolution was an event that took place ten years before its outbreak when Jim Smith and his Pennsylvania frontiersmen fought against the injustices of the thriving Indian trade. The events surrounding the tiny rebellion are told through young Jerry Wharton whose father is running a wagon train of supplies to the British garrison at Fort Pitt. When Braxton, a brigand, leads it, Jerry is taken along and rather shocked to find that materials for Pitt are merely a cover for goods to sell to the Indians- goods of the kind that will do little to make them more peaceable neighbors. Smith and his boys find the train. Their talk and their victory in a small battle convince Jerry of the good job they are doing protecting the frontier and he returns to persuade his father that the fight for social stability is more important than money.
