The head of a family of drifters urges his cardsharp son and saloon girl daughter to pose as respectable citizens while at Shiloh Ranch.

When Judge Garth is appointed Governor of the Wyoming Territory, he asks his Civil War friend Morgan Starr to take over running Shiloh in his place. Starr's hardnosed demeanor doesn't sit well with anyone on or off the ranch. His introduction is made harder by a locust plague when Starr decides to stay and fight them rather than move the cattle.
