Mainwaring prepares a poster for a recruitment drive, eager to increase his platoon to a company and so gain promotion to Major. A mix-up at the printer, though, lands the platoon in trouble and Jones, the face of the recruitment drive, in a prisoner of war camp.

To raise money for the Comforts For The Troops Fund, the vicar organises a bazaar to which each member of the platoon donates something. Hodges, the greengrocer, donates three oranges, rare due to wartime rationing. Mainwaring is determined to buy one of the oranges for his wife.
