Ross Bodine and Frank Post are cowhands on Walt Buckman's R-Bar-R ranch. Bodine is older and broods a bit about how he will get along when he's too old to cowboy. Post is young and rambunctious and ambitious for a better life than wrangling cows. When one of their fellow cowboys is killed in a corral accident, Post suggests a way into a better life for himself and his friend: robbing a bank. Bodine reluctantly joins in the plan and the two contrive to rob the local bank. They make good their escape initially, but Walt Buckman and his two sons, John and Paul, are incensed at this betrayal by their own trusted employees. John and Paul set out to bring Bodine and Post to justice.

Joe Lightcloud persuades his Congressman to give him 20 heifers and a prize bull so he and his father, Charlie, can prove that the Navajos can successfully raise cattle on the reservation. If their experiment is successful, then the government will help all the Navajo people. But Joe's friend, Bronc Hoverty, accidentally barbecues the prize bull, while Joe sells the heifers to buy plumbing and other home improvements for his stepmother.
