Undercover officer Nick (Daniel Wu) had spent the last seven years penetrating into the core of a drug ring
working his way up from a street dealer post to the managerial position handling cargo deliveries for Jong
(Andy Lau) - the biggest player in the local heroin market. When the ailing Jong makes Nick his prot�g�, Nick
could not but sway before money and power and starts to perform his role like a real drug trafficker. This,
together with his affair with heroin-addict Jane (Zhang Jingchu), causes Nick to becomes more and more
confused about his true identity, and eventually leads to a disastrous end.
