Prisoner Fu Yuan digs a tunnel in her prison cell and escapes. Inspector Song Donglu is summoned to investigate Fu's escape. By tracking down the letters sent to him by Fu, it sets Song off to Hong City to unravel Fu's disappearance.
IMO This show is not as good as the earlier series (The vanishing bullet).
The story line is too confusing, with too many characters having different plots. Each have their own motives but yet not clearly explained, making the audience difficult to focus.
End of day Inspector Songlu, did not really did some smart investigating like he did in the earlier version. Most of the events were revealed by the show, not by the inspector.
I could have mentioned so many parts that are meaningless or left unfounded for.
There seem to be focus on unnecessary action, dancing and music scenes, which is redundant to the core of this genre of show.
