Policeman Darren (Aaron Kwok) who was on vacation and his friend and partner Alex (Wang Leehom) attended the latter's girlfriend's fashion show together. They witnessed a murder case and immediately stopped their vacation to solve the case. During the investigation, the two found that the case was extremely complicated and involved a huge criminal organization in a city in the south of the mainland. After rushing to the city, the two met Interpol Norika (Fujiwara Norika) who went undercover to investigate a case involving an international criminal organization. In order to lure out the big fish, Norika took the risk of pretending to be a model on the catwalk, while Darren and Alex watched in secret. When they waited for the target person to have a gunfight with him, Alex was unfortunately shot and killed. Darren, who was extremely heartbroken, vowed to eradicate the gang, and he and Norika gradually developed feelings for each other.
