Tsui Wing Pong and Tsui Ka Lap are adopted brothers. Pong was sent to the Tsui family when he was very young because his biological father abandoned the family during a difficult period. Over the years, Pong bears a deep grudge against his biological father, who is the owner of the Yip family bank. At the same time, the Yip family had a dark past and some dangerous secrets. Lo Tzi Kin is the new head of Pong's division at the police station. He has a sister Lo Wai Fong, for whom Pong had an unrequited love. Kin was in love with Fong Hau Yung, who works at the bank run by the Yip family and so was she. But they were forced to give up on each other, due to some circumstances, and Kin ends up marrying Cheung Suet Ning, who is actually in love with Pong's brother, Tsui Ka Lap.
