 Jess Brady (Rex Reason) and Rupe Pardee (Richard Erdman) are in jail in Gunsight, Texas, blamed for leading a wagon train into a Comanche ambush, and about to be hanged. They protest their innocence and claim that the Indians want to kill them also. The Comanches attack the jail in an effort to capture the prisoners, but are driven off the soldiers of the garrison led by the Captain (Rusty Lane). Expecting another attack, the Captain and a small detail of men move the prisoners out of town in a wagon, but they are under constant surveillance by the Comanches. The detail arrives at a way station the same time as a stage coach carrying Marsha Collins (Nancy Gates), and her fiancee, Farley Durand (Robert Knapp), a government supply officer. All are trapped in the station which is under constant attack by the Indians. Brady and Durand resume a personal battle that dates back to the Civil War when they served together. The wounded Captain decides to gamble on Brady and Pardee, their expierence being the only hope for an escape. In the escape battle, it is revealed that Durand was responisble for the attack on the wagon train, and not Brady and Pardee.
