Frankie Chan plays Fan Kei (his cantonese name) who can read lips. He dubbs movies and helps some people with raw video footages by reading lips. But his job causes him big trouble. He finds about robbery plan. Police don't believe him, so he has to fight himself against the robber. He doesn't do it just for uncovering the truth, but also for saving his own life.
I enjoyed every minute of this movie. If you like Chan's other earlier works like Just For Fun or Perfect Match you should check this one.
