In a trench in France in 1917, during a heavy artillery bombardment, two
diggers are about to go over the top when a shell lands nearby. They
are joined by another soldier, just returned from leave, who conjures a
genie from a whiskey bottle and asks him to bring them Napoleon
Bonaparte. The diggers discuss the war with Napoleon before another
shell explodes nearby, and they are buried under a pile of dirt. When a
sergeant major pulls the men free, they continue their discussion with
the French emperor. The first two diggers are subsequently sent to a
clearing station as shellshock cases, while the third is sent on
fatigues.
