Larry (Kimbley) has now lost his mother. All he has left is his dog, Shep (Flame). When social workers try to separate the boy from his dog, Larry heads West. With the help of Manuel, a Mexican Immigrant (Garralaga), they reach Arizona. While stopping for gas and a meal, Larry is befriended by the local sheriff, Cap (MacDonald). When Cap is wounded in a robbery, Manuel becomes the suspect. It is up to Larry and Shep to bring the true criminals to justice. In the end, Larry and Shep have found a new home with the Sheriff.
