Cochise Springs rose from the hot, sunbaked earth like a series of low lumps of clay and rock. It was a one-street town but it offered Will and Gid Crockett the opportunity of a cold beer and a hot bath. There they meet a winsome young lass named Dora Walters. Dora tells them that her brother had been murdered by Rollo Doran, an outlaw cattle rustler whose perfidious activities are a threat to every rancher in the area. The marshal can't handle it, but the Crockett brothers can.
