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.

Can they leave their past behind and persevere in seeking the truth?
