Standard shooting stuff, with stress on racial strife, as Sheriff Luke Wheeler tries to prevent Spanish-American Juan Barristos and his sister from being driven out of Mt. Pisgah. Senator Lipsey, greedy to add the Barristos ranch to his own extensive range, is the instigator of the trouble, and keeps things stirred up. Boys are beaten, cattle are infected, and blame put on the Barristos. But Luke unmasks Lipsey and saves the day.
