Four international thieves disguised as wealthy tourists relax at a nightclub following their latest diamond heist, unaware of the police closing in on them. Ching, a hostess assigned to the thieves' table, recognizes the plainclothes police officers on the street, unintentionally enabling two of thieves, Ling and Hung, to escape. The remaining two thieves, Lo and Tam, are arrested and sentenced to prison, but the diamonds remain missing with only Lo knowing where they are hidden. One day, Ling and Hung contact Ching, who has since quit the nightclub, to request her help in finding Lo's sister to whom Lo might be willing to reveal the location of the diamonds. Initially reluctant to get involved, Ching joins in solely on the consideration that Lo's sister, an illegal immigrant, needs the money for living expenses. But before long, it emerges that Ling and Hung do not trust each other with the diamonds either, and Ching finds herself trapped in the middle of an escalating rivalry.
