Every clue serves as a silent witness against crimeBomb disposal expert YEUNG YAT SING (Kevin Cheng) returns from England to visit relatives and he comes across a grenade case by accident. With his tactful and level-headed approach, SING is highly appraised by Senior Chemist KO YIN POK (Bobby Au Yeung) and is being invited to join the Forensic Division. In a little while, SING becomes the division’s rising star. By work, SING gets back in touch with his long-lost best friend KOO CHAK SUM (Frankie Lam). SUM serves as a forensic writer and he is going to get married soon.
Accidentally SUM’s fiancée LAM TING TING (Linda Chung) is killed in an explosion and POK’s police girlfriend LEUNG SIU YAU (Yoyo Mung) also loses the ability of holding a gun in the incident. YAU’s duties are passed to MA KWOK YING (Charmaine Sheh) from the Narcotics Bureau. Both SUM and SING find YING extremely charming with her smart and unfathomable characteristics in case handling.
Integrated the laboratory techniques, logical reasoning and forensic knowledge, the trio strive to fight against crimes tremendously. As they get to know each other more and more, the entangled triangle of love also starts to hinder their working relationships.

Bobby Au Yeung: His character was interesting, very smart and lots of scientific things to learn from this series and from what he's saying. But they should of put more Bobby and Yoyo scenes.
Yoyo Mung: Maybe they shouldn't of made yoyo go to another country to study, I missed seeing them. But I even missed seeing Linda and Frankie!
Charmaine Sheh: Charmaine's role was fun to watch! Very cold! But when she smiles, she looks pretty. Charmaine's real person, she smiles all the time but in this role, she's has to be COLD. Very interesting to watch. I kinda enjoyed watching her and Kevin. But I still like watching Linda and Frankie more. And also Charmaine's acting was great! Especially the last episode where in 10seconds, she has to have an expression of touched to cry out loud.
Kevin Cheng: His character was kinda funny somehow... I also liked parts of him with Frankie. Brotherly Love?! Especially where the bomb bombed them in the boat.
Frankie Lam: I missed sooo much seeing him and Linda. But it was good that they added Sharon Chan in the last episode. Hope to see a FH3!!!
