My Mother-in-Law Guards Our Home

Xiuyun, nine months pregnant, is gentle and kind. Just as she's about to give birth, her husband Zhang Fugui is caught in a tryst with his mistress Xiao Tao at home, only to be discovered by Fugui's mother. Having long disliked Xiao Tao, and to avoid upsetting heavily pregnant Xiuyun, she lies that Xiao Tao is a distant cousin. Learning that Xiuyun received land compensation from her family, Xiao Tao seizes the chance to play pitiful and move in, scheming to swindle the money. Once inside, Fugui's mother constantly targets Xiao Tao, forcing her to wash clothes, chop wood, and cook, while guarding against her seducing Fugui or harming Xiuyun.
