Set on the Alpine Front of World War I, between 1916 and 1917, the film follows an Italian infantry division trapped in a brutal stalemate across a barren highland. Their sole objective is clear: retake a commanding height from Austro-Hungarian forces. The division is led by General Leone, Alain Cuny, whose approach to victory relies on frontal assaults against machine-gun positions, a tactic that prioritizes pressure and tradition over flexible tactics. The unit's commander, Lt. Ottolenghi, Gian Maria Volonté, oversees the frontline troops as they endure long days in trenches and the constant thunder of artillery.
As casualties mount, indignation and fatigue spread through the ranks. In a moment that exposes the human cost of command, a beloved junior officer is killed during an attempted mutiny, an event that rattles the soldiers and unnerves the chain of command. The film doesn't linger on heroics; it shows how quickly fear and anger can ripple through a unit.
In a stark display of military discipline, every tenth man of the battalion is chosen to be executed by a firing squad of his comrades in reprisal for the killed officer. This brutal mechanism of punishment underscores the moral ambiguities of war and the way orders can collide with conscience, pushing men to question what they are fighting for.
Among the soldiers, Lt. Sassu, Mark Frechette, emerges as a focal point. His experiences on the line sharpen his doubt about the war's purpose and pull him toward reevaluating where his true duties lie. As he witnesses his superiors' decisions and the consequences of those decisions, Sassu's inner conflict grows, revealing a path that leads away from blind obedience and toward a deeper contemplation of humanity and duty.
The film's tone remains somber and observational, offering a clear, morally complex portrait of World War I trench warfare: the allure of a quick tactical win against a deadly machine gun, the exhaustion of soldiers who are asked to push beyond their limits, and the heavy price paid when leaders let ambition trump prudence on the fog-shrouded Alpine front. In the end, it paints a stark picture of a war that tests the limits of loyalty, courage, and conscience on the fog-shrouded Alpine front.
