A dying wife had the best of intentions for her husband and three sons. Ling Hau (Louise Lee) was dying of cancer and wanted to make sure her husband, Tong Yan Gai (Ha Yu), and sons, Chi On (Moses Chan), Chi Yat (Bosco Wong) and Chi Yan (Fala Chen), were taken care of. So she arranged a new wife for Yan Gai with Frances Wong Sau Kam (Susanna Kwan), and she bore him a son, Chi Foon (Lai Lok Yi). But things get complicated when Hau unexpectedly survives, leaving Kam with no legal standing or respect in the Tong family. As Kam plots to inherit the family fortune for herself and Chi Foon, it takes all of Hau’s energy to stop Kam and throw her out of the house, resulting in a relapse of Hau’s cancer. With the help of Chi On’s attorney friend, Sheung Joi Sum (Linda Chung), can the Tong family stop Kam’s evil plot and restore the family’s peace? “Heart of Greed” is a 2007 Hong Kong drama series. It was followed by the sequel “Moonlight Resonance” in 2008.
