After shooting a Western in the wilds of Wyoming, screen cowboy Jeff Carson decides to stick around for awhile to help his pal, Shakespeare Holmes, get over a messy divorce by roughing it for a while. Traveling incognito, the two get jobs as real cowhands, and no sooner do they get their gear to the bunkhouse than they're caught up in a range war. A crooked Cattleman's Protection Bureau is extorting money from local ranchers, and those who refuse to cooperate are harassed or killed. The outlaws even come up with the novel idea of using a low-flying plane to stampede their victims' herds. Jeff calls on a pilot friend of his to fly to Wyoming and join in a search for the mystery aircraft. After a deadly aerial duel brings the outlaw flier down, Jeff decides to take his air war to the gang's hideout.
