The series covers the tiger mother phenomenon, where children are deeply influenced by a strict and autocratic parenting style.

Meanwhile, her husband Yim Ha, who has a softer approach in raising their children, faces a midlife crisis and the temptation of an extramarital affair, which estranges the couple.

Despite being extremely strict with her children, Natalie is very tough and often contends with another member of St. Gabriel School's parent-teacher association (PTA), Rebecca Yuen.

Natalie wants her children to be successful academically, but finds out that Venus is dating Claire's younger brother, Hayden Man.
