Buddy goes West

In the West a mysterious man, nicknamed "Doc", arrives in a dusty town. Doc is a bandit who robbed a city physician, keeping his instruments' briefcase. He is misunderstood by local residents for a real doctor, and induced to care in particular for sick children. While treating them, Doc becomes aware that the small town is harassed by a criminal gang that bribes the sheriff. Doc immediately proclaims himself the new sheriff, and proceeds to hunt down the bandits.
