"Big Sister" Mo Wanwan is known not only for her famous nasi lemak, but also for her Herculean strength, huge appetite and rotund build. Yet, she hasn't always looked like that. The hefty-sized Mo used to be a pretty, svelte girl, and had a daughter, Lin Siting, with Lin Jingcai at the age of 18. Jingcai then brought the baby back home to be taken care of by his wife Su Yueping, who is unable to conceive. Ever since Jingcai was put behind bars for a crime he committed, Yueping forbids Wanwan from seeing Siting. The 2 women are always squabbling, and are known as 'the most quarrelsome duo in Holland Village'.
