Ying is an unassuming nightclub employee in Macao who alienates a gang of drunken men. They tail her after her shift, and mount a gang assault. She attempts to enlist the aid of her former brother-in-law - an ex-triad now confined to a wheelchair. A lounge owner in HK, he hires her as a waiter and finds her a place to live, but refuses to help in her quest for vengeance. She, however, has other ideas.
