context: As seen in flashbacks that occur throughout the film, Oliver Woodward is an Australian miner supplying copper for the war effort. He falls in love with Marjorie Waddell, a young woman ten years his junior. However, he is under constant pressure to enlist, especially from Waddell's father. He has the opportunity to do so when the British Army forms the 1st Australian Tunnelling Company to supplement the Royal Engineers; Woodward is commissioned to lead the unit.
  On the Western Front, Woodward meets Frank Tiffin, a young Australian soldier who is suffering from shell shock. Woodward reassigns Tom Dwyer and Norman Morris to relieve Tiffin. Two German tunnelers break through into the tunnel. Morris and Dwyer dispatch both of them, but Dwyer is killed when a German explosive goes off, bringing down the tunnel on top of them; Morris is rescued by the other sappers.
  Woodward is later tasked with destroying the Red House, a fortified German position raining enfilade fire down upon the frontmost section of the British trenches. Although Woodward initially proposed tunneling beneath the Red House, his commanding officer, Colonel Wilson Rutledge, insisted that it be done by dawn. Along with Corporal Bill Fraser and Morris, Woodward crosses No Man's Land. They manage to reach the Red House and plant explosives underneath it. However, as they make their way back to the British lines, they discover that the reel of cable is too short, so Morris runs ahead to retrieve the exploder. While they wait, they discover mortally wounded Lieutenant Robert Clayton, who had been ordered to cut a gap in the wire obstacle for them. Morris arrives with the exploder and they destroy the Red House.
  The next day, after a friendly game of rugby league against some British soldiers, Woodward is promoted to captain and he subsequently promotes Fraser to Sergeant, he later receives word that they are to be moved up the lines to the Ypres Salient. Upon their arrival, Tiffin, Walter Sneddon and Billy Bacon are separated from the rest of the battalion and pinned down by German machine gun fire. Bacon, being the fastest runner, volunteers to distract the Germans while the others make a run for the British lines. Although Tiffin and Walter succeed, Bacon is killed mere inches from safety.
  The unit continues on to Hill 60. During an inspection, it is revealed that the Canadian Engineers have been tunneling deep below the Messines Ridge for months, planting a million pounds of ammonium nitrate in the form of 21 massive mines. Woodward is tasked with maintaining the tunnels as the British military buildup begins; they hope to kill as many German troops as possible. To this end, he constructs an enormous shaft to keep the water table from inundating the explosives. He also digs multiple diversion tunnels to throw the Germans off. Jim Sneddon (Walter's Dad), is buried in one such tunnel when he is ordered into it by Colonel Rutledge, despite reporting that the Germans would likely be setting off the explosives soon.
  The Germans eventually catch on to their plan and dig toward the main tunnel. An attack tunnel is dug in response, and the Australians successfully destroy the exploratory shaft with minutes to spare. However, the charge that was used weakens the clay and a portion of the tunnel collapses, trapping Tiffin. His compatriots race to stall the detonation of the mines, but the schedule cannot be delayed on account of one man. Woodward detonates two of the mines fired at the start of the Battle of Messines.
  Woodward returns to Australia and the surviving members of the unit gather for his wedding with Marjorie.
