In 1880s Tascosa, Texas, Marshal Guthrie McCabe is content to be the business and personal partner of attractive saloon owner Belle Aragon, receiving ten percent of the profits. When relatives of Comanche captives demand that Army Major Fraser find their lost ones, he uses a combination of army pressure and rewards from the families to get the reluctant McCabe to take on the job of ransoming any he can find. He assigns Lt. Jim Gary, a friend of McCabe's, to accompany him.
