Devil's Doorway

Lance Poole, a Shoshone Indian, won the Congressional Medal of Honor for his service in the Civil War. Lance is ignored by the white townspeople, who are against him and his father because of their hold on the richest land in the region. When Verne Coolan, a prejudiced lawyer, threatens to take Lance's land away under a new homesteading law, Lance hires Orrie Masters, a female attorney who has recently settled in Medicine Bow, to take his case.
Lance and his Shoshone Indian fighters take refuge in Lance's cabin, and quickly turn it into a makeshift fortress. After calling in U.S. Cavalry troops, Orrie makes an unsuccessful attempt to persuade Lance to give up his losing fight.
Lance kills Coolan, but when the Cavalry fighters join the sheepherders, Lance's men are overwhelmed and forced to surrender. Lance gets shot. In the final moments of his life, gives the Cavalry commander a farewell salute.
