At the foot of the Continental Divide, rancher Frank Redmond struggles to maintain his land amidst the bleakness of Depression-era Montana. Married but childless, Frank's wondering if the long-term future of the ranch is worth the effort. For that matter, he's considering much the same about his wife Abby. When a stray dog wanders onto the ranch, Frank's first impulse is to shoot it as vermin. Abby and Clay, Frank's father, insist on adopting the mutt, naming it Stranger.
