Drifter Sam Bass shows up in Denton, Texas (soon to host a great horse race) looking for work. Before long, he attracts the attention of pretty storekeeper Katherine Egan (the sheriff’s sister) and that wild frontiers woman, Calamity Jane. Circumstances make Sam richer by a very fast race horse. But his seemingly good luck with horses and women leads him to disaster. Will he be forced into a life of crime?
