 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.
