A blizzard threatened the North Dakota Badlands, and Dwight Jerome was herding his father's sheep across the road back to the ranch. That was when he first saw the magnificent big mutt who filled the back seat of a car from New York.
When the storm broke, the Easterners were afraid of being snowed in for days in the car. They abandoned the dog.
The big mutt slept out the storm in a coyote's den. When he awoke, he was famished-and this nose led him to sheep.
To the ranchers, any dog that kills sheep is doomed. A posse is sent out to track the outlaw down. But Dwight believes the wolves are doing most of the slaughter, and he is determined to save the big mutt.
