Mike (Shawn Yue) is the police officer with the highest crime-solving rate in Hong Kong. This is because he is rich, or more precisely, his father is rich. Using money as bait and bribing informants with money has made his crime-solving record rise repeatedly, and he has also earned the title of "Flower Police" from his colleagues. No one believes that he can solve a case without money. During a case, Mike once again caused big trouble for the police force - he sprinkled money from the air, causing traffic paralysis - so he was suspended. Lin Heng (Chen Kun), who also came from the mainland to investigate the cause of his brother's death, happened to know Mike. On the day they met, the two wore the same suit and tie. It was a fate in the dark. What's more coincidental is that Mike's ex-girlfriend Lisa (Linda Chung) is inseparable from Lin Heng. One wants to find out the real murderer, and the other wants to prove his ability. Lin Heng and Mike travel together. Starting from getting clues, they gradually find that they have been led into a trap by the murderer. The two have established an extraordinary friendship in the midst of danger, but the ending is not as beautiful as we thought.
