Heart of Greed - Season 1

Tong Yan-Gai (Ha Yu) owns dried sea products and abalone store along with 31 shops for rental. He has a total net worth of HK$600 million. He is married to Ling Hau (Louise Lee), a rich man's daughter, and he also has a second wife called Wong Sau-Kam (Susanna Kwan), a former nurse who had previously taken care of Hau when she had cancer. Gai has 4 children: Tong Chi-On (Moses Chan), Tong Chi-Yat (Bosco Wong), and Tong Chi-Yan (Fala Chen) by Ling Hau and Tong Chi-Foon (Lai Lok-yi) by Wong Sau-Kam. Hau had not expected to survive her bout with cancer and wanted Kam to take care of her husband after she died, but she recovered.

Kam thinks that she has no power in the family because she has no true status, as she is not legally married to Gai. She becomes a woman who instigates a range of petty acts that tend to come back to haunt her. She seeks the family fortune, and in order to do that, she causes trouble in the family.
