When his cattlemen abandon him for the gold fields, rancher Wil Andersen is forced to take on a collection of young boys as his cowboys in order to get his herd to market in time to avoid financial disaster. The boys learn to do a man's job under Andersen's tutelage; however, neither Andersen nor the boys know that a gang of cattle thieves is stalking them.
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.
