The ambush on the Durango caravan fails and Chris Trenton, massacrer of Comanchesgets blown up in a wagon full of dynamite! A short while later, a band of buffalo exterminators scatters rotting carcasses, infecting the Ute reservation: two shady individuals from Monticello move behind the scenes of the useless massacre, the speculator, Nick Barrow, and Cristian Mayer, a greedy Indian agent who issues hunting permits in exchange for ready money. Tex is the one who cuts off their criminal career.
