Montana Territory, 1886

'The last thing this territory needs is Indian trouble, or a bunch of nervous settlers demanding protection by the Army. As United States Marshal for the territory, I figure to send Jeff a little help...I figure to send him you,' he said.

U.S. Deputy Marshal Merlin Fanshaw arrives at the Crow Indian Reservation with orders to restore law and order. But a powerful rancher and his son block the deputy's efforts in order to retain their rigid control over the nearby settlement of Medicine Lodge. When a shocking murder rocks the town, tension and violence escalates between the Crow Indians and the settlers. Fanshaw must bring in the killer before an innocent man loses his life - or he forfeits his own.
