The sheriff of Gunlock is planning to hang Sam Hall, who shot three farmers found on cattle land, at sundown. At the casino, betting is 8 to 3 he won't make it. The cattlemen are set to rescue Sam; the farmers hope to lynch him before he can be rescued; and Hall schemes for escape with his girl Nellie. But Sheriff Jorden is most concerned with finding out who hired Hall: a leading suspect is the sheriff's future brother-in-law.

Three outlaws rob the stage and then flee. When their horses give out they murder some Indians to get fresh ones. But this puts the Indians on the war path and they have to take refuge in an Army fort to avoid them. The Indians then arrive offering peace if the three men are turned over to them. The fort's commanding Officer wants peace but the rules say the men must be tried in a white man's court leaving the Indians no choice but to attack.
