When Rawhide Robinson, babysitting a herd of beeves on a train bound for Chicago, reads about a rat infestation in the mining boomtown of Tombstone, he hatches a plan that results in yet another string of extraordinary adventures. Retired mountain man Longshot Hawken shows the way down the Santa Fe Trail. Arlo Axelrod ramrods a reluctant cowboy crew of Zeb Howard, Johnny Londo, Tony Morales, and Frenchy Leroux. And as if handling an unpredictable herd wasn't trouble enough, the shiftless Buckskin Zimmer does his best to do the worst to crew and critters. Then, the designing Don Carlos Valencia's woeful wooing of the magnificent Magdalena Maria Martinez y Montez de Monterrey forces her to throw in with the cowboy band in an attempt to escape his clutches. And all along the way, Rawhide Robinson holds the enterprise together as he meets every adventure head-on, and regales his drovers—and anybody else who will listen—with campfire tales of insane adventures, exploits, and escapades experienced elsewhere during his extraordinary cowboy career on the western frontier.
