Tong Yan-Gai (Ha Yu) owns a dried sea-products and abalone store. He has 4 children: Tong Chi-On (Moses Chan), Tong Chi-Yat (Bosco Wong), Tong Chi-Foon (Chris Lai) and Tong Chi-Yan (Fala Chen). He is married to Ling Hau (Louise Li) and has a second wife called Wong Sau-Kam (Susanna Kwan). Hau had cancer and didn't expect to survive and wanted Gai to be happy with another woman and wanted Kam to take care of him after she dies, fortunately she recovered. Kam thinks that she has no power in the family because she has no true status and becomes a woman stirring a range of petty acts that tend to haunt her in full circles. She seeks the family fortune and in order to do that she causes trouble in the family. Hau, a wise lady pulled the family back together and turned their frowns into smiles. Unfortunately, Hau's cancer resurface and she dies leaving her struggling family behind.

They plotted for years to find a means to take the family fortune and even created public false accusations about her own family in the media. Kam formed her own support group from the worst family members and in-laws to help plot against the Tong household to gain their family fortune.
