When Kin (Tony Leung Ka-Fei) asks his wife May (Brigitte Lin) to steal money from her employer to repay gambling debts, he expects her loyalty to outweigh her morals. However, May refuses, and the rejection sends Kin into a rage. Ultimately, he plans to eliminate May by making her death look like a suicide. But when May survives his plot, how will she take her revenge?
