Shitou is a young man. His grandfather is a well-known hunter. Due to the war, Shitou dropped out of school. He likes to go hunting with his grandfather.
After Japan launched the September 18th Incident, the people of Northeast China rose up to fight and spontaneously organized teams to resist Japan. There is an anti-Japanese team in the forests of Changbai Mountain, led by General Cao and Erduodao.
Liu Weilin, Shitou's Mandarin teacher when he was in junior high school, was still teaching. The Japanese took control of the school and demanded that Japanese language and Japanese history be taught. Liu Weilin was secretly engaged in anti-Japanese propaganda activities. He helped the helpless woman Xiaohong, and the two got along with each other for a long time. In order to educate students, Liu Weilin took the risk of taking a Chinese history class, and then fled to the customs with Xiaohong.
In order to eliminate the anti-Japanese troops, the Japanese organized a crusade into the mountains. Suspecting the villagers to be bandits, they began to massacre the village. Shitou's family was killed. Only Shitou survived. He came to the mountain and asked to join the volunteer army, and General Cao accepted him. Shitou, who was bent on revenge, worked hard on his marksmanship and finally became a sharpshooter who frightened his enemies.
The days of the Anti-Japanese Alliance became more and more difficult, and the conflict between General Cao and Er Duidao intensified. General Cao suspected that Er Duidao had betrayed them. Er Duidao took people down the mountain, but encountered the enemy. The two were arrested, and they refused to surrender after being tortured, and were eventually killed. After General Cao found out, he was determined to avenge the two swords. They attacked the enemy camp.
The enemy launched a frantic counterattack, and General Cao's most trusted lieutenant betrayed the enemy. The Volunteer Army suffered huge losses, and in order to preserve its strength, they withdrew to the Soviet Union. Shitou has grown into a brave and tenacious warrior, and he stayed to continue the anti-Japanese cause.
