Will Penny an aging cowpoke takes a job on a ranch which requires him to ride the line of the property looking for trespassers or worse squatters. He finds that his cabin in the high mountains has been appropriated by a woman whose guide to Oregon has deserted her and her son. Too ashamed to kick mother and child out just as the bitter winter of the mountains sets in he agrees to share the cabin until the spring thaw. But it isn't just the snow that slowly thaws; the lonely man and woman soon forget their mutual hostility and start developing a deep love for one another.
