When a shady organization blackmails her nation's embassy into becoming a casino, the ambassador's daughter Sarah seeks out a gambler who can bankrupt the casino and comes across con artist Matsunaga Hisahide. After agreeing to the job, Hisahide manages to challenge the CEO to an all or nothing game of poker. Hisahide allegedly loses the match, but it turns out to be a distraction so her accomplices can steal all the money from the casino's safes.
