Master Constable Luk Chin (Yuen Wah) fell in love with the female outlaw Fei Ying (Michelle Yim) and they have a daughter - Luk Sap Hei (Niki Chow). Hoping to follow in her father's footsteps, Luk Sap Yee (Niki Chow) is an impulsive and idealistic constable whose skill and competence is often dismissed by her corrupt male peers.
