- Raised by Tiger Mom-Eliz Yu, stay-at-home mom Natalie Cha, who is deeply influenced by her strict upbringing, adopts an autocratic parenting style to raise her two daughters. It leads to resentment among them, especially for her elder daughter Venus Yim. 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. The two eventually become friends, thanks to Natalie's friend and the dean of discipline at St. Gabriel, Claire Man.
Natalie wants her children to be successful academically, but finds out that Venus is dating Claire's younger brother, Hayden Man. Eventually, a secret Natalie has been keeping for over a decade comes out into the open, souring the mother-daughter relationship.
