The Wei family has a strict iron rule: lunch must be served sharply at 12 p.m. every Sunday, and the entire family will face standing punishment if anyone is late. The patriarch Stanley Wilson is stubborn-minded and enforces his strict family code to control the household, leading to constant conflicts within the family. His daughter-in-law Jane Taylor is clear-headed and resolute, refusing to endure and compromise blindly. Jane's husband Zane Wilson gradually comes to his senses amid repeated disputes. The whole family redefines kinship boundaries amid conflicts, breaks free from outdated traditional concepts, and strives to pursue their respective happy lives.
