CHO KWAN YEUK-NAM (Selena Lee, Liza Wang) is a legendary woman. Ever since her husband CHO WAN-HON (Wayne Lai) committed suicide due to a business failure, she has brought up her three sons and one adopted daughter on her own, and single-handedly established a world-renowned business empire in the process. Gradually, she starts cultivating her sons to be her successors, including her eldest son CHO CHI-WANG (Kenny Wong), second son CHO CHI-YUEN (Hawick Lau) and youngest son CHO CHI-KO (Edwin Siu). Yeuk-Nam’s adopted daughter CHO HAU-YEE (Kimmy Tong) is so enamored of her second elder brother Chi-Yuen, whose heart however belongs to someone else. Later, following his romantic setback, Chi-Yuen devotes himself to his career, putting his eldest brother’s status as an heir in jeopardy. Out of the blue, an ambitious girl, SUNG CHI-WAH (Monica Mok), shows up in Chi-Wang’s life, and the two even collude to incarcerate Chi-Yuen. Just as the whole family is on the verge of crisis, the real identity of lawyer MOK NGA-MAN (Angie Chiu) is unveiled, and meanwhile, Hau-Yee also returns. So, how is Yeuk-Nam, an incredibly accomplished woman, going to tackle all of these variables?
