Dad's Army

Walker is discovered transporting Italian prisoners of war out of the camp under cover of darkness. Rather than acting as a traitor, his covert activity actually supports the war effort, provides him with a side income, and helps to undermine enemy operations.

is an episode‑length programme that forms part of a larger series. It is presented as a self‑contained story, falling squarely within the episode genre, and its title hints at the boundaries its characters are willing to cross. The central narrative follows Walker, who is discovered in the act of moving Italian prisoners of war out of a camp under the cover of darkness. His nocturnal activities are initially portrayed as a breach of military protocol, and the moment he is caught suggests a serious offence. However, the episode makes clear that Walker’s conduct should not be read as treasonous. Rather than undermining the Allied cause, his actions are shown to bolster the war effort, implying that the prisoners he helps to relocate are being used in a way that benefits the fighting forces. The storyline positions his smuggling as a covert contribution rather than a betrayal. In addition to serving a strategic purpose, Walker also gains a personal advantage from his clandestine work. The narrative notes that he is able to line his own pockets while carrying out these operations, indicating that his motives are partly financial. Thus the episode paints a picture of a man who walks a fine line between duty and profit, using the chaos of war to further both the collective cause and his own interests.
