A trail drive is coming to an end, with the resulting payoff of the now out-of-work trail hands. A trio of punchers, Blue, Dutchy, and an aging Will Penny decide to drift south and avoid the oncoming winter. Will trades his position riding on the train with the cattle to a young cowboy who wants to visit his dying father and tells Will there may be work at the Flat Iron ranch.
One morning Blue is about to fire at a bull elk near a river bottom. Mysteriously, the elk is shot by an unseen party. As Blue and Dutchy move in to claim the elk anyway, they encounter the shooter, a "rawhider" and his family. The two groups contest the right to the meat. Gunfire erupts, and Will shows up, shoots and kills one of the rawhider's sons. The rawhider swears a biblical revenge. Dutchy accidentally wounds himself in the exchange, so the trio head out to find a doctor and first come to a nearby trail store, where they encounter Catherine Allen and her son Horace. After getting a few drinks of whiskey they move on to the nearest town and leave Dutchy at the doctor. Blue decides to look for a job in the town, while Will proceeds alone. He comes across a horse without a rider and locates a dead cowboy, thrown from his saddle. Will turns the body over to the Flat Iron ranch that the cowboy rode for and is offered a job.
Will hires on to ride the far-off boundaries of Flat Iron ranch over the winter. As he arrives at the upper range, he finds Catherine and Horace staying in the line-rider's cabin after being abandoned by their guide. He rides away to inspect the fence line, warning them that they must be gone when he returns in one week.
The next morning as Will is sleeping outside near the fence, he is ambushed and savagely beaten up and knifed by the rawhider group. They rob and leave Will for dead, but he drags himself to the cabin, where he is slowly nursed back to health by Catherine.
As the winter passes, Will and Catherine fall in love, and Will develops fatherly affection for Horace.
As Will and Catherine prepare for Christmas, the Quint family bursts into the cabin, force Will into doing the chores, and coerce Catherine to decide on one of the ne'er do well, belligerent, hair-trigger sons. After some days, Catherine distracts the two Quint sons so Will can make an escape. At that same time his two former saddle pals Blue and Dutchy arrive looking for him. Will and Blue return to attack the cabin to free Catherine and Horace, using a bag of sulfur in the chimney to smoke out the rawhiders and then shoot them all.
With the rawhiders dead the Flat Iron trail boss arrives, Will realizes that he is too old and set in his ways to settle down into a domestic life with Catherine, against her protestations. Deeply regretful about what he is leaving behind, he rides away with Dutchy and Blue to collect on a bet with the store owner on Dutchy's survival and continue his life as a trail hand. He donated his wages from the ranch to Catherine.
