A soldier in a gas mask walks through a war-torn landscape with burning debris and smoke under a bright sky. The scene shifts to a soldier in a biplane firing a machine gun at enemy aircraft and ground targets over a battlefield. The view changes to a soldier in a forested area firing a weapon, causing an explosion. The scene cuts to a soldier in a military uniform running through a dark, damaged interior. The final scene shows soldiers in combat gear advancing through a war zone with explosions and gunfire.
