Crab is a smooth professional gambler, although "con man" might be more accurate to describe some of his sleazy and deceptive means by which he tricks his rich victims out of huge amounts of money. Although it must be said, he never steals from the innocent, but only slimy business tyrants. His friend and gambling partner, Law is arguably the more careless of the two. They are called in to assist a Casino owning friend of theirs who has lost a lot of money to some cheating Japanese Yakuza, and so their investigation into the suspected men ensues. Needless to say, this attracts unwanted attention and eventually leads them into trouble with the Yakuza. When Law's girlfriend, Tong is kidnapped by the Yakuza in exchange for Crab, a punishment for stealing back some money in a gamble, Crab goes straight after the kidnappers.
