一个是商界大亨,有财有势,在黑白两道呼风唤雨。一个是阻街流莺,放荡不羁。一个是女警校刚毕业的学生,充满了正义抱负。钱多了找点小刺激把这三个不同背景的人连在一起,引发出一连串的事件……May Lin is a loudmouthed and boastful hooker, whose life dramatically changes when her room-mate Nana is nearly beaten to death by a masked client, then killed in hospital. A bunch of gun-toting goons (sporting sunglasses and suits) chase May. She goes into hiding, then contacts Prosecutor Yin Li Shin, who believes her innocent. Yin sends his niece, hot-kicking policewoman Nancy Cheng, to arrest and protect May. Nancy takes a bullet protecting May, and they gradually become friends. Later, May sees political candidate Kao Tien Chin and identifies him as Nana's masked assailant. But how to prove his guilt?
