During the "cold gun and cold artillery" campaign of the War to Resist U.S. Aggression and Aid Korea, Ren Dongfeng, who had been in the army for two years, showed his excellent shooting talent in a battle for a position, but also caused his comrades to die under the enemy's sniper gun, which became a shadow in his heart. Gao Zhankui, the squad leader of the "special shooting squad", took Ren Dongfeng under his command against all odds, and the good old man Wang Qing became Ren Dongfeng's observer. They launched a heroic sniper battle with the U.S. sniper ace Shulman on this cruel battlefield.
