Plot

After he drifts into town with Fairweather, a card-playing partner, Cruze accepts a job as town marshal and takes on the corrupt Moran brothers, cattle rustlers who are cheating rancher Charlotte Downing and her brother Cass. Cruze had previously been a lawman in another town but when the townspeople turned its back on him and refused to help out in his hour of need, Cruze vowed to never wear another badge. The same thing seems to happen in his new job until he discovers that Fairweather is not a "fair weather friend".
