Indian Inspector James McLaughlin finds himself recently removed from a fateful order to arrest Sitting Bull, which led to the famous warrior and medicine man's death at the hands of his own Sioux people. McLaughlin is now tasked with brokering a deal between the Shoshone and Arapahoe in newly formed Wyoming. The two tribes are traditional enemies but find themselves as neighbors on the reservation and partners in a potential deal to sell part of their land that includes the sacred waters. McLaughlin must use his knowledge of the West and his mistakes of the past to broker a deal that is fair and upheld by both sides of the deal, no matter the stakes.
