Mainwaring swells with pride when told seniority earns his platoon being the honor guard during PM Winston Churchill's visit to inspect the coastal defenses. Alas, their awful performance at the target practice range in front of major Regan questions their suitability. HQ grants them one chance, a champion trios contest against the Eastgate platoon. Short of crack-shots, Walker 'recruits' Laura La Plaz, a vaudeville's South American sharp-shooter for the occasion. The contest provides some surprises.
