Inspector Lu Fei of the Chinese Police lives and works in a normally quiet rural area of Northern China. But the recent crackdown on wet markets - where unusual live animals are sold - has led to a marked increase in the smuggling of exotic animal parts into China. Lu Fei and his team have been directed to run sting operations to catch the local sellers of these illegal things. However, a young girl, Tan Meirong, has shown up at the station to report her fifteen year old sister, Meixiang. Meixiang has been working as a waitress at a club in the nearby city of Harbin to support the family but hasn't been heard from recently. Despite his superiors complete lack of interest, Meirong shames Lu Fei into investigating - and what he finds is that Meixiang had been working at a club catering to the local elites and disappeared immediately after an incident at the club. Fearing the worst, Lu Fei taps his sources and follows a trail that leads him to the source of much of the smuggled animal parts in the area - a warlord in nearby Myanmar. Going undercover, unofficially, to find the missing girl, Lu Fei finds himself in the middle of a very dangerous compound with almost no chance of survival, much less success.
