On the run from a posse with a price on his head, legendary gunslinger Billy the Kid (Buster Crabbe) and his partner Fuzzy Jones (Al St. John) make their escape with the help of local rancher Ed Dawson. They return the favor by helping out at Dawson's run-down Circle X Ranch. Recent violence on the trail has left Dawson shorthanded for an upcoming cattle drive and he fears deadly sabotage at the hands of the rival Double Box Ranch. Undaunted, Billy agrees to lead the drive and take on the Double Box's shadowy gunmen. Best known for playing Flash Gordon in several successful serials, Buster Crabbe spent much of the '40s acting in assembly-line westerns, including thirteen Billy the Kid films for PRC Pictures between 1941 and 1943.
