Bomb disposal expert Yeung Yat-Sing, Ivan, (Kevin Cheng) returns from England to visit relatives and happens to come across a grenade case by accident. Ivan's skills are highly appreciated by Senior Chemist Ko Yin-Bok, Timothy, (Bobby Au-Yeung) and he is invited to join the Forensic Division. Ivan soon becomes the division's rising star.

Ding-Ding dies of her injuries, while Siu-Yau loses movement in her right hand and goes half-deaf. Yau's duties are passed to Ma Kwok-Ying, Bell, (Charmaine Sheh) from the Narcotics Bureau. Both Sam and Ivan find Bell extremely charming with her smart and unfathomable characteristics in case handling. Then Ivan fell in love with Bell and the two become a couple.
