The story of this drama happened around the Zhongtiao Mountain Campaign in the middle period of the Anti-Japanese War. It tells a story about a young master living in a rich family who grows into a hero while spilling blood with the Japanese invaders and fighting side by side with the Eighth Route Army. At the same time, Ji'er, a female soldier of the Eighth Route Army, Dachun, the company commander of the Eighth Route Army, Su Yunxiao, Long Shao's first love and her husband Wenxuan, Long Shao's little brother Stone, as well as the Japanese cold-blooded sniper Jesuit, are all famous for their guns, so this is also a legendary TV play about how to kill enemies skillfully with guns.
Young Master Long Shaoin, who has received regular training as a sniper at a German military academy, returned to the front line of the domestic anti-Japanese war with a heart full of enthusiasm for killing enemies and serving his country, but he was not adapted everywhere. Finally, he came to Section One Duan's Brigade. His first mission was to lead a small team to snipe a Japanese artillery team. When the task was over, he encountered the encirclement of the Japanese army, and almost wiped out. Only Long Shaoin escaped.
Long Shaoin returned to the troops and suspected that someone had betrayed this action. But Wenxuan, the intelligence chief of the Military United, suspected Long Shaoin why only he escaped? At the same time, Long Shaoin's lover since childhood, Su Yunxiao, also appeared in this regiment. Originally, she married this suspicious chief of staff, which made Long Shaoin think of leaving again.
However, the battlefield situation has changed, and Long Shaoin can only continue to perform the next task. This mission is to cover the transfer of troops. The Lin Regiment of the Taiyue Military Division of the Eighth Route Army is responsible for responding to the Nationalist Army's regiments. Long Shaoin fought shoulder to shoulder with the company commander Dachun of the Eighth Route Army for the first time. Although there is a huge gap between the two sides, they cooperate seamlessly in sniping the enemy. Then the Japanese army sent a top sniper Jesuit, who trained in the same school as Long Shaoin, to sneak attack on Duan's headquarters at night. The intelligence was intercepted by the Eighth Route Army, so the Eighth Route Army took the initiative to act and smashed Jesuit's sneak attack together with Duan's Brigade. Ji'er, a female soldier of the Eighth Route Army, was wounded while rescuing Long Shaoin. This gave Long Shaoin more opportunities to know the Eighth Route Army.
Wenxuan found out that Long Shaoin and Jesuit were classmates, and he became more suspicious of Long Shaoin. However, Long Shaoin's performance on the battlefield was highly recognized by Duan, the professional military commander. Wenxuan also found that his wife Su Yunxiao's feelings towards Long Shaoin were unusual. The two had different dreams. And Su told Long Shaoin that Wenxuan was the best man in the world. In fact, because her child was held hostage by the Japanese army, Su Yunxiao had been forced to become a spy for the Japanese army.
