Texas Ranger Tom Bell is simply tracking a fugitive killer in 1931 when he rides into Kilgore, a hastily erected shanty town crawling with rough and desperate men—oil drillers who've come by the thousands in search of work. The sheriff of the boomtown is overwhelmed and offers no help, nor are any of the roughnecks inclined to assist the young Ranger in his search for the wanted man.

In fact, it soon becomes apparent that the lawman's presence has irritated the wrong people, and when two failed attempts are made on his life, Bell knows he's getting closer to finding out who is responsible for cheating and murdering local landowners to access the rich oil fields flowing beneath their farms. When they ambush him for a third time, they make the fatal mistake of killing someone close to him and leaving the Ranger alive.

Armed with his trademark 1911 Colt .45 and the Browning automatic he liberated from a gangster's corpse, Tom Bell cuts a swath of devastation through the heart of East Texas in search of the consortium behind the lethal land-grab scheme.
