Her Judgement Day.

Tough, oversexed Ching Tse and her pubescent cousin possess acassette of triad boss' names -- and a rival gang wants to get their hands on it. All would be hopeless if not for studly Sam, whose appearance is hardly accidental. The movie's climax is its sole justification: Sam switches sides and fights the enemy in a huge garage aided by a gang of good guys on scooters, while Ching rescues her cousin.
