Macau's largest cruise ship, the Oriental Pearl, was slowly sailing on the high seas. This gambling competition was a private duel, where the loser would exit the gambling industry in Macau. One could say that, in a sense, this was a duel that involved the life or death of both parties.
The guests invited to observe this gambling showdown aboard the Oriental Pearl were all magnates of Macau's gambling industry. Their influence was such that a single stomp of their foot could shake Macau thrice over. Therefore, to ensure the safety of the event, all individuals were prohibited from bringing any weapons aboard, even private bodyguards were not allowed.
