Jordan McAllister and her quirky friends are celebrating Cinco de Mayo this year at a new casino in Oklahoma, compliments of recent acquaintance-famous New York chef George Christakis. With margaritas flowing and Mexican cuisine piled high, the weekend promises to be one big party. However, Jordan can't help herself and snoops her way into a scheme involving casino chips. The stakes are raised when the lead singer of the casino band turns up missing and more than one person has motive to want her out of the picture. It's assumed the high-maintenance woman ran off with the CFO of the casino, especially when it's revealed they were having a tryst, and that he's also gone missing.

But after a local rancher, who believes the casino property was stolen from him, makes a scene at the resort and ends up in the secluded wine room with a gun to his head and Jordan as his sidekick, it becomes obvious that losing a few bucks at the blackjack table may be more than either of them gambled on.
