Tao Qingchuan builds a snake-repelling biological isolation belt in the back mountain. Her second aunt Liu Cuihua and cousin Zhao Xiaoqin force her to shovel it up to expand their chicken coop, even signing a liability waiver for self-borne losses. As pythons and snakes descend the mountain one after another, the mother and daughter suffer heavy losses yet repeatedly frame and stir up trouble, and even deliberately damage the defenses multiple times. Tao Qingchuan makes all-around preparations, leads the rural breeding cooperative to drive villagers to get rich, repeatedly brings out evidence to neutralize the other party's malice, and finally, the evildoers of the Zhao family are punished according to law, while the village develops steadily through ecological protection and characteristic industries.
