The Wangs keep a harem of concubines.

However, Wang Jianzhi chooses to endure this disgrace silently and bear the adultery. Mother, who used to be a maid of the Wangs, actively joins in the anti-Japanese battle of the village and becomes a revolutionary mother who later learns how to tactically fight against the brutal enemies. Juanzi, daughter of Mother, falls in love with Jiang Yongquan, a young promising party secretary in town, but is obstructed by Zhao Xingmei, head of Women Association. Head of the arsenal, who dies a glorious death and is Xingmei's husband, turns out to be Juanzi's elder brother.

Unfortunately, Xingli is brutally raped and killed. That extremely cunning spy is later arrested, and confesses that his boss is the seemingly vulnerable woman whose real name is Shima Hanako, a senior Japanese spy of Special Division.
