While on a trip to buy cattle, Colonel MacKenzie becomes involved in the affairs of a woman reporter and a group of former Comancheros who are now trying to make an honest living raising sheep. In writing a story about the group, the reporter has mentioned their hunting down of a maverick steer. Gossip in the nearby town fails to note that the steer was a maverick, and a group of cattle ranch workers respond by killing the sheepherders' entire herd. The leader of the former Comancheros, Sosentes, responds by kidnapping the reporter and holding her for ransom. Unfortunately, MacKenzie finds that the local sheriff's hatred of Comancheros far exceeds his concern for the woman's safe return.
