Several Indian tribes claim that white men are kidnapping their women and children to be sold for slaves or held for ransom. In order to prevent an all-out war with the local tribes, the U.S. Army sends Bat Masterson to investigate.

Bat rides into town to meet a young friend. He arrives too late - the young man was killed when he accused three wealthy ranchers of cheating at cards and the sheriff refuses to arrest the men responsible for the murder.
