Chung Shun and Chung Ching are two brothers working in the Criminal Intelligence Bureau (C.I.B.) of the HK Police Force. Shun heads the technical section of the unit while Ching is part of the intelligence assessment section. Working in the C.I.B is challenging and stressful as the bureau is involved in tackling organised crimes. Shun and Ching's family and relationships are affected due to this.
Shun is married to Emily and has a teenage son, Michael. After 10 years of marriage, their relationship is no longer how it used to be. On the other hand, Ching begins to develop a relationship with Samantha, who coincidentally is Emily's nemesis at work. Samantha is a very focused and determined person at work and Emily sees her as a threat.
