Lin Zhenguo, a cook, encounters a Vietnamese special agent team while delivering food. He kills an enemy sniper with a pole and is discovered to have extraordinary battlefield intuition. After being transferred to the Sharp Knife Company under special circumstances, he not only had to face the ghost killers deep in the jungle, but also had to crack the enemy's carefully laid "strangulation net" plan. When it is discovered that the mercenary organization "Blood Sickle" has built a secret tunnel in Qingyun Ridge, this soldier, who was once nicknamed the "Firehead Army" by his comrades, will use the captured SVD sniper rifle to rewrite the entire war situation.
