Dee is a disheveled, hot-headed HK cop; Apple Yu is an urbane, designer-dressed inspector from the ICAC. Now, they're partners trying to bring down (still another) triad crime ring. To intimidate Apple, Dee dresses like a model, but finds that her partner has taken on a street-punk guise to intimidate her. They locate a priest who's a triad defector; and while Dee takes a nun's guise, her partner tries to pull off being a junkie in withdrawal.
