In the law of the gun, a man must shoot his way to innocence. At least that's how Captain McKelly of the Texas Rangers puts it to Buck Duane. On the run for killing a man to save his own skin, Duane must now infiltrate the deadly Chelsedine gang. These ruthless rustlers are running amok in Texas and it's going to take a matchless gunfighter to stop their rampage. With the legendary Rangers providing firepower, Duane has more than a fighting chance. Or so he thinks. When he uncovers a secret that could destroy them all, the bullet storm is biblical - and a legend rises out of the dust.
