Once a Black Sheep

The film follows Dee, a disheveled and hot-headed Hong Kong cop, and her partner Apple Yu, an urbane inspector from the ICAC. Together, they aim to dismantle a triad crime ring using unconventional tactics. Dee's attempt to intimidate Apple by dressing like a model backfires when she discovers that Apple has adopted a street-punk look to challenge her.

As the story unfolds, Dee and Apple engage in a series of disguises, including Dee's nun costume and Apple's portrayal of a junkie in withdrawal. Their antics provide a mix of action and humor, making the film a noteworthy entry in the action genre of the early '90s. The film features a talented cast, including Carol Cheng, May Lo Mei-Wei, and Kenny Bee, each contributing to the dynamic of this unconventional partnership.
