In this remake of Gene Autry's 1942 "Call of the Canyon", Rex Allen, the newly-elected head of the cattleman's association, is driving the combined herds of the ranchers to the nearest railhead when he runs into trouble. The drive is stopped by Brock Stevens, whose father is a power in the meat-packing industry, and whose ownership of the railroad spur line enables him to deal ruthlessly with the local ranchers. Rex and the other ranchers are elated when Brock agrees to pay fair-market price for the cattle until they learn the exorbitant loading fees he charges will eat up their profits. The only alternative is to drive the herd to the main line railroad at Big Bow.
