Wang Bo(Andy Lau) and Wang Li (Rene Liu) should have made the perfect Bonnie and Clyde: the former a seasoned con mean and master pickpocket from Hong Kong, the latter a grittier femme fatale from Taiwan. Partners in crime and passion, the couple swindle their way across China, until one fine day Li suddenly decides to call it quits, both to her egregious lifestyle and to her entanglement with Bo. It is at this crossroad in their lives and relationships that they run into Fu Gen in a train station, an encounter that will alter their fate forever.
