Little Larry Havens, an orphan boy, whose father died in WWII, on his way to live with his uncle picks up a stray dog, and the two become fast friends. However, the uncle doesn’t want the dog, and when chickens are found dead, the uncle accuses the dog of killing them. The boy decides that it’s time he and the dog hit the road so they run away, to keep from being separated from Shep. In Arizona, he is befriended by  kindly  Manuel Ortiz, who he is able to repay in time, with the aid of Sheriff “Cap” Weatherby, when Ortiz is suspected of crimes committed by local gangsters. “Shep” is instrumental in saving Ortiz from a lynching, and Larry, “Shep” and Ortiz all find a home with a couple they have befriended.
