A series of unfortunate events has led Makoto Edamura to adopt a life of crime—pickpocketing and scamming others for a living. However, after tricking a seemingly clueless tourist, Makoto discovers that he was the one tricked and, to make matters worse, that the police are now after him.

While escaping, he runs into the tourist again, who turns out to be a fellow con man named Laurent Thierry and follows him to Los Angeles. In an attempt to defend his self-proclaimed title of "Japan's Greatest Swindler," Makoto challenges his rival to determine the better scammer. Accepting the competition, Laurent drops them outside a vast mansion and claims their target will be the biggest mafia boss on the West Coast.

As Makoto becomes increasingly involved with the cunning Laurent, his colorful associates, and the world of international high-stakes fraud, he soon realizes that he got more than he bargained for as his self-declared skills are continually tested.
