This drama is also that final series that stars Aaron Kwok and Athena Chu filmed for the television station.

Yeung Tai-chi (Aaron Kwok), a newcomer investigator of the ICAC, is met with frequent failures, but he remains optimistic.

Chiu Wing-yee (Athena Chu), also a new member of the ICAC, is so aggressive that she always challenges Chi.

Police officer Yau Lok-sang (Ben Ng) gets to know Leung Siu-man (Esther Kwan), who is blind, by chance.

In the course of investigation, Chi is forced to make decisions between love, friendship, family and justice, and has difficulty in facing the dilemma.
