There's big trouble for Texas cattle ranchers.  A mysterious disease called "Texas Fever" seems to follow their herds to market.  Now their steers may be banned from Kansas and the railroad -- a measure that will spell ruin for them all.  The governor's ready to do anything to find a cure, even pardon a man with a price on his head, Waxahachie Smith.

The scheme is all Captain Dusty Fog's idea.  He knows Wax dreams of coming home to Texas where he's a wanted man.  Now  Wax can return if he takes over the protection of a brilliant young vet who may be close to a breakthrough cure.  But unscrupulous men will gain if the Texas cattlemen go under.  And with flying bullets and hired killers getting ever closer, Wax needs to use his famous slip gun to even the odds -- to draw fast, shoot  straight, and fight to the death to clear his name.
