Western Australia, May 1915. Archy Hamilton (Mark Lee), an 18-year-old optimistic rancher with a knack for sprinting, is mentored by his uncle Jack (Bill Kerr) as he dreams of following in the footsteps of his idol, world champion Harry Lascelles. As World War I rages on, Australia recruits young men to assist the British, and Archy, wanting to honor his country, is determined to enlist in the Light Horse. In a thrilling opening scene, he showcases his speed, completing a 100-yard sprint in an impressive 9.58 seconds.
During a cattle roundup, an explosive argument with local bully Les McCann (Harold Hopkins) leads to a barefoot race against him, which ends in Archy’s victory but leaves his feet badly injured. As Archy recuperates at home, he becomes engrossed in Jack’s reading of The Jungle Book, especially a poignant moment about Mowgli’s coming of age, which resonates deeply with his own aspirations.
Eventually, Archy and Jack head to a nearby athletics carnival. There, they meet Frank Dunne (Mel Gibson), a down-on-his-luck railway laborer who narrowly loses to Archy in a race. Afterward, Archy decides to enlist, handing Jack his prize money but keeping his medal and Jack's stopwatch. Jack reluctantly permits Archy to enlist, foreseeing the perilous path ahead.
However, Archy faces a roadblock: he's underage, and the local recruiter won’t accept him. In a local tearoom, he confides in Frank, who then proposes they travel to Perth to enlist. With no money, they hop on a freight train only to find themselves stranded in a remote desert station. The station attendant presents them with a choice: wait two weeks for the next train or trek 50 miles across the desolate landscape. Archy, undeterred, immediately sets off, prompting Frank to pursue him, warning of the dangers of the barren wilderness.
After an encounter with a camel rider, they spend the night at a cattle station, then make their way to Perth, where they stay with Frank’s father. Although Frank is reluctant to fight for the British due to his Irish heritage, the spirit of camaraderie compels him to join the Light Horse alongside Archy. Unable to ride, he enlists in the infantry with his friends Billy (Robert Grubb), Barney (Tim McKenzie), and Snowy (David Argue), all drawn by a mix of patriotism, adventure, and societal pressure.
Fast forward to July 1915, Frank and his companions are trained in Egypt near the Pyramids, indulging in leisure activities and expressing disdain for British command. Fate reunites Frank and Archy during an unceremonious training exercise, and after a brief transfer, they prepare to depart for the Gallipoli Peninsula.
Upon their arrival at Anzac Cove, perilous trench warfare awaits them. The ANZAC forces find themselves cramped against the shore, conducting their lives amidst the chaos of battle. One fateful night, Frank connects with his mates who are about to enter the brutal Battle of Lone Pine. Here, he discovers the heartbreaking news of his friends Barney and Snowy, revealing the harsh realities of war.
Archy and Frank are swiftly drawn into the Battle of the Nek, a critical maneuver intended to distract the enemy during the British landing. As Archy bravely volunteers to be a runner, he refuses to leave Frank behind. Their commander, Major Barton (Bill Hunter), thrusts Archy into a daunting role that requires extraordinary courage.
The Australian Light Horse, comprising 300 brave troops, is positioned to execute their charge at dawn. Yet, everything goes awry when a calculated delay gives the Turkish defenders ample time to prepare. As waves of soldiers rush into the fray, they are met with devastating gunfire. In a moment of chaos, Archy spots Les among the attackers and witnesses the shocking fate that befalls him.
Frank finds himself racing against time to convey critical information to halt the assault—truth he knows will come too late. The misguided instincts of their commanders lead them to a tragic fate, as Archy, along with his comrades, is driven into a final, futile charge.
With shadowed anticipation, the soldiers are allowed their last moments of reflection. As they leap into the fray, the air is thick with an all-too-familiar dread, knowing they are marching toward certain death. Archy, fueled by instinct and survival, races across no-man’s-land until, just shy of the enemy’s trench, he is hit by merciless machine-gun fire, becoming a haunting emblem of war's horrific toll.
The closing image, reminiscent of Robert Capa's poignant photograph of a dying soldier, captures Archy as he succumbs to his wounds, a stark reminder of the bravery and tragedy entwined in the fabric of war.
