Cass Callicott, a famous old Buffalo hunter, arrives in North Fork and makes a point of introducing himself to Lucas and Mark. He explains that he has been called the best in the country with a rifle; although, he has heard of Lucas' reputation with a rifle. He challenges Lucas to a target shoot, but Lucas refuses, sure that he would beat an old man who's not as good as he used to be. Cass mistakes Lucas' refusal for cowardice and suddenly turns vicious. The old man announces instead of targets, he will prove his prowess by shooting Lucas. McCain still tries to avoid a fight, but is forced into one when Cass kidnaps Mark.
