Sulla pista di Fort Apache

Elizabeth is headed to Fort Apache, Arizona, to marry Lieutenant Parkman, an inept officer who caused the Indians to rebel and then let the rebels led by the ferocious Chunz escape. The patrol escorting the girl to the military garrison is attacked by those rioters and only the audacity of Tex and Tiger Jack, who are looking for some Navajos who have fled to join Chunz, and the Laredo scout saves the woman from a bad end.

Meanwhile, the Indian guide Lobo and Tiger Jack save Curtis' ranch from annihilation and find the rebels' lair, ending up prisoners! Tex and Laredo manage to save only the Navajo pard from death by torture and run to Fort Apache to raise the alarm, not knowing that the redskins have kidnapped Liz! However, the two are arrested by the evil Lieutenant Parkman, who is about to torture some harmless Coyoteros to obtain information. The Laredo scout frees Elizabeth from the camp of the rebel Apaches. Meanwhile, the column of the cowardly Lieutenant Parkman, who arrested Tex and Tiger Jack believing them to be accomplices of the rebels, is attacked by the Indians. The good Sergeant Quincannon frees the pards and the battle heats up! Willer captures one of the Navajos who had abandoned the reservation to follow Chunz and orders him to bring an ultimatum to Cardona. The sakem accepts and his Coyoteros leave the warpath.
