Hide hunters, hunters who kill buffalo for their hides only, have temporarily joined up with the wagon train. One of their number, Gib Ryker, is a sociopath who enjoys antagonizing young Barnaby West. With the train desperately needing fresh meat, Cooper Smith, along with Barnaby, sets off with the hide hunters to look for buffalo. Along the way Gib continues to bait Barnaby, much to Coop's dismay until Barnaby is forced to defend himself, with disastrous results. Now Barnaby has to face Gib's brother Zach, who's out for revenge.
