A bond is formed between a doctor who cannot save lives, a policewoman who cannot catch criminals and an assassin who cannot kill, but can they solve crimes? Failing to protect a key witness to an international drug smuggling case, Interpol Officer Xu Guo Ying (Denise Camillia Tan) resigned as a result. She meets funeral planner Wang Yu Xuan (Sheryl Ang) and arcade staff Chen Zhi Ming (Desmond Tan), together the trio form a team that specializes in the search for key witnesses in unsolved cases. They soon forged a strong friendship but each is not what they appear to be. As their past catches up with them, it threatens to destroy them. A doctor who cannot save lives, a policewoman who cannot catch criminals, and an assassin who cannot kill, how will their lives unfold? Can they leave their past behind and persevere in seeking the truth?
