Young Billy Freeman (Billy Lee) is caught trying to pilfer from the till of the store he works for. A Delinquency Court inquiry by Judge Roger Davis (Bradley Page) and attractive Welfare representative Joan Allen (Kay Linaker) uncovers some disturbing facts - that Billy stole to bail his dog Pal out of the Dog Pound, and that his father William Freeman (Addison Richards) - whom Billy hero worships - is a single, frustrated and now alcoholic Army veteran. The Judge and Joan Allen, who are romantically involved with each other, begin taking a personal interest in this dysfunctional family. Responding to Billy's and William's desire to have at least one Freeman in the Armed Services, the Judge and Joan facilitate the dog Pal's enlistment into the Army's Dogs for Defense program. Pal undergoes rigorous training in anti-sabotage, combat and disarming techniques and emerges as Billy and William's pride and joy. In their involvement with the Freemans, the Judge and Joan find their personal relationship thriving, too. When William Freeman relapses into alcohol abuse, thereby disqualifying himself from re-enlistment, the Judge pulls some strings with an influential Army supplies manufacturers and gets him a job there. Soon, Pal is assigned on Army Security duty at the same plant and becomes instrumental in foiling a sabotage attempt in which William Freeman is killed under heroic circumstances. The Judge and Joan, having decided to marry, adopt Billy into their new home.
