Guilty of the slaughter of Kalabah’s peace-loving Native Americans and of the murder of two of Piccolo Falco’s Navajo friends, the Yuma Policemen, led by Sergeant Wolson, are tied up by Tex and Tiger Jack and taken back to Fort Whipple to have justice done. Wolson, who was hunting down Na-Ta-Wah, an Indian scout accused of murder, maintains that the patrol had been attacked, while Tex is certain that it is a matter of a tribal revenge! During a heated discussion, Kit Willer ends up in the lock-up and is helped to escape by his father with the complicity of some gold diggers.
