In "Death for Double-O Neighbors," Tom Lucas owes plenty to Old Bob Hurley who raised him and helped him start up his own ranch, the Wagon Wheel. Lucas is also in love with Old Bob's granddaughter, Marcia, who has just returned from the East. Hurley calls a meeting of all the small ranchers, for which Tom is a leader, to warn them a range war is headed their way if the skimming off of his yearlings doesn't stop. Lucas is torn by his loyalty to both Hurley and his Double-O Ranch on one side and to the small ranchers on the other. That loyalty is tested when his ranch is burned out and he and his partner are branded cattle thieves by Hurley himself.

When Stanley Blanton, an engineer charting the mineral resources of the Northland in the "Out Trail," crashes through a snow bridge with his sled and dogs, he injures his ankle. Two hundred and fifty miles from food and shelter for both himself and his dogs in the midst of a blizzard, all hope seems gone until a sled team appears in the distance. Knowing the code of the North—that one must to help another in distress—Blanton calls out, but the man and his team pass him by.
