Young Johnnie Tanner didn't know how to shoot, camp out, or even ride a mule, but more than anything else he wanted to go to the Wild West... Then he got his chance. Along with Hank Raney, a grizzled, sharp-shooting cowboy who taught him Western ways, Johnnie hit the trail. Little did he know that he would soon find himself stalking a magnificent white buffalo worshipped by the Indians as a sacred beast, battling savage Pawnees who lusted for the white man's blood, and above all, hunting down a vicious thief called Pawnee Harry who had stolen a fabulous pearl from Johnnie and then escaped into the wild, untamable mountains of the American West!
