Something fishy is going on in the anti-Drug Trafficking Unit of the HK Police, and only a few honest cops know that the corruption goes all the way to the top. However, they must prove their case quickly, and by unconventional means, after they are framed for murder and drug-trafficking themselves. Dodging bullets from cops and criminals alike, the race is on to clear their names, protect their loved ones, and bring their corrupt colleagues to justice.

Millionaire playgirl Ling Young (Michelle Yeoh) spends her free time staging elaborate heists -- not for the money but for the thrill of getting away with it. As part of her latest plan, Ling recruits a team of professionals from around the world to steal billions from an armored car on a Hong Kong highway. Lucky for Ling, the insurance man (George Lam) hired to bring her to justice is too smitten to stay objective.
