Ranch workers disguised as soldiers murder Indians in order to stir up trouble with the whites so the rancher can claim their land.
Plot
Landowner Morton wants to expand his property because he knows about oil deposits under the Indian territory. Settlers also come to the area, as a peace treaty with the Comanches provides security. Disguised as soldiers, Morton has his men attack the Indians. Black Eagle, the chief of the Comanche, then digs up the hatchet. After a bloody raid, the village's surviving settlers seek shelter in the nearby fort commanded by Captain Jackson. Due to the peace treaty, however, the garrison is undermanned and Jackson is unable to act. He hires trapper Clint McPherson to investigate the cause of the Indian uprising, uncovering Morton's deceitful plan, which he tells Black Eagle. He and the Indians arrive at the fort just in time to assist the soldiers and settlers against the attack by Morton's men.
Production
Jack Lewis recalled that Ron Ormond asked him to write a draft of a script based on a magazine story called Fort Disaster adding Indians, cavalry and Frank and Jesse James. When Ormond passed on the screenplay, Lewis retitled his screenplay Massacre Mountain and gave it to his agent Ilse Lahn Waitzerkorn[1] who several years later leased his script to Constantin Film.[2] The Germans used the screenplay to bring back Tony Kendall as Black Eagle from The Pirates of the Mississippi with his frequent film partner Brad Harris. Joining Harris was his future wife Olga Schoberová who appeared with Harris in Massacre at Marble City.
