It's the last day on the job for Marshal Morg Rocklin who plans to get married. The new Marshal is due in town the next day. Unfortunately, a bunch of troublemakers are in town. Among them is rancher Joshua McCloud's no-good son who's bringing in a herd of cattle for sale. Immature, spoiled and quick tempered, the McCloud boy gets into an argument with his cowhands in the saloon and shoots one dead. The Marshal tries to arrest McCloud's son who draws on the lawman and gets killed. Postponing his wedding, the Marshal rides out to break the sad news to old rancher McCloud who has recently taken a young gold-digger wife. The old man drinks too much lately. The Marshal fears the worst for his meeting with the old rancher who doesn't yet know that his son was killed. To make matters worse, Bart Thorne, the McClouds' head ranch boss hates the Marshal and wants him dead.
