Attending a reunion, two Australian ex-servicemen reminisce about their exploits in France during WW1. These include lying in a field hospital where they feigned deafness to extend their recuperation, stealing jars of rum from the Quartermaster and inventing an elaborate ruse to hide them and finally, the night before returning to the front relaxing in a French café where romance blossoms between the soldier and waitress as told through the song 'Mademoiselle from Armentieres'.
