The old comrades are called up for three weeks of autumn maneuvers. They are usually more interested in beer, girls, and cheerful music, but Sergeant Vældegaard is determined to scrape the civilian rust off the "boys." Their old friends from their days as recruits have remained in the system as platoon leaders and sergeants, respectively, but that does not dampen the fun. In the heat of battle, the schoolteacher finds time to flirt with his Lotte Corps colleague Birthe.
