Man with a mission ...Danny Fog has a lot to live up to, being the younger brother of Dusty Fog, the legendary gun wizard from Rio Hondo. But Danny's still a lawman to be reckoned with -- and by breaking up the loathsome cow-thieving outfit that's terrorizing Caspar County, he'll be well on his way to writing his own legend. The gun-crazy outlaws and Mexican cutthroats standing in his way shouldn't be too much of a problem for the big and brash young Texas Ranger. But dealing with the lady boss of the rustlers may be more than he can handle without help. So Danny's going to fight female fire with female fire, joining forces with one Martha Jane Canary. But kicking in with this tough gun-toting senorita could be more trouble than Danny Fog bargained for ... once he learns first-hand why folks hereabouts call her "Calamity."
