Bad Traffic is a kind of modern-day noir thriller:  instead of set in 1950s Los Angeles, though, it's set in present-day Britain.  Instead of featuring hard-boiled private eyes and gangster dames, it features a tough Chinese police officer who comes to Britain to investigate his daughter's disappearance.  He's thrust into a world of illegal immigrants, Chinese gangsters and the restaurant industry, where he doesn't speak the language, is running out of money, and can't figure out what has really happened to his daughter.  Inspector Jian ends up with an illegal immigrant named Ding Ming as his hapless sidekick; Ding Ming speaks English and serves as translator and mapreader while Jian follows the trail left by his daughter.
