Zhao Laokai is a guerrilla, and his son Daliang also joined the guerrillas. During a Japanese raid, Daliang Niang was too ill to escape and was killed by the Japanese. Zhao Laokai rescued Suhua on the way to escape. Suhua later became Daliang's aunt and regarded the rescued girl Xiaoxiao as her own. As Zhao Laokai's youngest son, Liangliang is deeply loved by his family, especially his sister-in-law Suhua. At a commendation meeting in the village, Liangliang went home alone while his father was not paying attention. He encountered a hungry wolf on the way and was rescued by the district team and villagers who arrived in time. At the same time, he repelled the Japanese invaders who came to rescue the hungry wolf.
