context: The main character is Sergeant Michael Dunne (later reverting to his mother's maiden name McCrae for re-enlistment), introduced in the spring of 1917 after Vimy Ridge, a decorated veteran of the 10th Battalion, CEF.
  During heavy combat in a ruined town, Dunne is wounded and sent home from Europe as a neurasthenia patient. While recovering from his injuries, he meets nurse Sarah Mann (Caroline Dhavernas) in Calgary, Alberta, where he had originally enlisted.
  Sarah Mann is drummed out of the local nursing service, and ostracised in town, because her father was of German descent and had left Canada to rejoin the Imperial German Army in 1915. He was killed at Vimy Ridge on the opposing side to Sergeant Dunne. She has become addicted to morphine as a means of dealing with the recurring loss in her life.
  David Mann (Joe Dinicol) is Sarah's younger brother. Despite being ineligible for military service due to asthma, he is desperate to win the respect of his girlfriend's father at a time when military service is demanded of all young men. He is vehemently anti-German and tries to expunge the fact that his father was German, and had died fighting for Germany, from the family history. His girlfriend's father pulls strings to get him enlisted, arguably in the hope that he will not return and marry his daughter. Sarah originally thinks Michael has enlisted David, in his role as local recruitment officer, but later finds this is untrue. The enlistment is further facilitated by a British recruiting officer whose malice and goading of David Mann and Michael Dunne makes him the film's principal antagonist. Michael however feels a responsibility and re-enlists as Private McCrae in order to protect David at the front.
  As a result, both David and Michael end up in the battlefields of Belgium. Sarah also enlists and follows the 10th ending up as a nurse in triage at an Advanced Dressing Station near the front. The three arrive in Flanders in time for the Battle of Passchendaele. Dunne and Sarah soon meet up again when Dunne brings a wounded man to the aid station. Although Dunne's cover as McCrae is soon blown, he manages to escape punishment and is promoted to platoon leader by Lieutenant Colonel Ormond, who knew him from earlier fighting, when his past actions "should have got a V.C." and because of the need for experienced soldiers as high casualties were expected.
  When the Canadians launch their attack, the 8th Battalion (Winnipeg Rifles), known as the Little Black Devils, faces a German counterattack and become pinned down. Dunne's company is sent to support them. After the support company arrives, the 8th Battalion retreats from the battlefield, wrongly believing that they are finally relieved, leaving the job of holding the ground to Dunne's small force. As the reality of the war begins to set in, David Mann begins to realize the war was not what he believed it would be. Dunne's forces spend the night in their trenches, and as a result of the shelling, David begins to have an asthmatic/panic attack and Dunne calms him down, relieving the problem.
  The next morning the Germans counter-attack, and make it as far as the line, and both forces attack each other in close quarters combat. As the Germans retreat, David breaks down and chases them back to surrender. He jumps into their trenches and is met by a gun to the face where he begs in German. He is about to be shot when an artillery shell lands and the explosion throws him onto what is effectively a cross, created by walkway timbers from the trench. He is visually crucified by the explosion. This relates to Dunne's earlier story of the legendary report of the crucified soldier. When Dunne sees this he takes his helmet off, throws his gun down and runs to David, in a reckless attempt to keep his promise to keep him alive, getting shot in the process. He crawls to the cross on his knees, looking up at it. The Germans stop firing and allow him to retrieve David, whom he carries back to his own lines. The fighting swiftly resumes with a shell landing. David lives, but Dunne is carried to the hospital where he dies after his last words with Sarah. This happens just as the news comes in that the Canadians have captured Passchendaele Ridge.
  The ending scene shows the wheelchair-bound David Mann (now only with one leg); Sarah Mann; David's girlfriend Cassie; and Dunne's best friend Royster (Gil Bellows) paying tribute at Dunne's grave on his home farm. The marker has been altered to remove the "5" of 1915 and changed to 1917. The camera then pans out and the background alters to a field of hundreds of Canadian war graves with a riderless horse on the horizon.
