During the Battle of the Somme in 1916, French corporal Jean Le Maire gradually grew into the core of the team from a "survivor" who was initially afraid of war and only wanted to protect himself. From resisting the German chlorine-phosgene hybrid bomb attack, cooperating with the British Mark I tanks to break through the defense line, to night attacks on the German chemical ammunition depot, and launching life-or-death duels with the ace sniper "White Death", Jean Le Maire combined Chen Hao's "wretched flow" tactics with his own battlefield intuition in countless actual combats, leading the team to escape from death every time. During this period, he witnessed the sacrifices and trauma of his comrades, met non-facial German soldiers, and gradually understood the cruel nature of war.
In the cruel background, the bonds of the little people and the glimmer of peace are retained, and finally a World War I epic about growth, responsibility and perseverance of humanity is presented.
