Mrs Ko, Tung Kwok Hing (Rebecca Chan) adopted an orphan and claimed he was Ko Yi Ho (Raymond Wong), the illegitimate child that her husband Ko Siu Tong (Samuel Kwok) had been searching for many years. Tong believed Ho was more suitable than his oldest son Ko Yi Tai (Joel Chan) to be his successor, which later led Mrs. Ko's discontent. Eventually Ho was kicked out of the family, leaving him homeless. Living out alone, Ho got a taste of the bitterness in life and was determined to return home and take revenge on his adopted family under a different name Tung Bun Sin. Under his new identity, he vowed to give them a taste of losing their loved ones. Meanwhile he runs into the naive, trusting Tsui Sum (Niki Chow), who had just taken over her family business. Seeing an opportunity, Ho deceives Tsui Sum of her family business and all her familys' money in order to get closer to the Ko family. However, old ties, secrets and memories of a childhood sweetheart come back to haunt him, and Ho eventually embarks on a road that threatens the lives of all he holds dear, and the life of the only woman he's ever loved.
