However, Judy's other dog Smoky escapes and he is found by thieves Mort Gunning and 'Red' Fargo. Gunning and Fargo train Smoky so he can help them rob fox farms. After a theft at the Freeman Fox Farm belonging to Rod and his young son Billy Freeman, Judy is the prime suspect because her dog Smoky was recognized in the robbery.
