It tells the story of the patriotic awakening of villager Zhao Xiaotian. Under the high pressure of the Japanese devils' burning, killing and looting, he wanted to live a life of shame, but was involved in the struggle with the Japanese army by mistake. Zhao Xiaotian was originally a wild and naughty rural youth with his own little thoughts. He was delicate, warm, weak, and lacked heroic temperament. His original purpose of joining the anti-Japanese team was just to avenge his relatives and marry his beloved girl as soon as possible. With the help of Jiang Dajiang, the captain of the New Fourth Army guerrillas, Zhao Xiaotian gradually grew up, understood the national justice, strengthened his revolutionary beliefs, and gradually grew into a strong revolutionary fighter. He and his comrades used homemade mine tactics to repeatedly attack the Japanese devils who came to sweep, and finally eliminated all the Japanese troops entrenched near Zhaojiaji, becoming a well-known anti-Japanese hero.
