Hoping that the stay in prison in inhuman conditions will bring him to a gruesome end, the jailer Murdock shuts Tex in a hellish iron cage red- hot from the sun! But Murdock’s accomplice Clem, who was supposed to bump Willer off in an escape, makes a double deal with Carson. In the meantime, the shadowy high-ranking enemy who intends to get rid of Aquila della Notte in order to get his hands on the gold in the Navajo reservation, has a new Indian agent nominated, Larry Lyman, who he hires. But the Indians, guided by Piccolo Falco, won’t hear of leaving their territory.
