Big Jake Motley has been running the Big M spread in Texas for over thirty years. In that time, he's driven thousands of head of cattle to market in Kansas. Now, while both the nineteenth century and the era of the trail drive are coming to an end, Big Jake is determined to make one last drive to Kansas. The only catch is that he doesn't have the cowhands to move that much beef. He drafts his old friend Chance McCandles into service, and the two aging cowboys put together a crew.
