Retired uncle Li Jianguo, his enthusiastic wife Wang Xiulan, his son Li Wei, a rookie in the workplace, and his quirky granddaughter Niu Niu, a family of four lead an ordinary but lively life. Until his niece went on a business trip and entrusted a black cat named "Biuqiu" to her door, the peaceful life was completely broken - Uncle Li used his experience in feeding chickens to feed the cat and changed the cat food to millet; Aunt Wang's cooking of dried fish triggered a "cat chasing battle" for the whole family; Li Wei's "cat-raising strategy" was completely ignored by "Biuqiu"; only Niu Niu could get along with this "naughty ghost". From the crazy trusteeship farce to the whole family becoming a "briquette support group", this daily fireworks caused by the black cat hides the most authentic family warmth and laughter.
