The main actors involved in this production were Moses Chan, Linda Chung, Louise Lee, Ha Yu, Michelle Yim and Susanna Kwan.

[2] Tong Yan-Gai (Ha Yu) owns dried sea products and abalone store along with 31 shops for rental.

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.

Hau is unable to speak, but she finally mutters a few words only audible to the ears of her son Tong Chi-Foon.

Kam starts to make plans to steal the family fortune with Sheung Joi-Duk (Lei Seng Cheung), and together, they cause trouble.

After meticulously planning with Kam, going as far as to give slander to the Tong family, she also drives Gai to severe illness and eventually dies from a stroke.

This resulted in Heart of Greed being only 2 points behind the highest rated drama on TVB in the 2000s: Dae Jang Geum.

The sales presentation clip was released on November 19, 2007, which featured Michelle Yim as the new villain and a mooncake business instead of Heart of Greed's abalone.
